Time Is No Longer the Friend of Darwinism

Today's neo-Darwinian scenarios have always relied on an abundance of time as an essential component of diversification through adaptation. We've all heard the canard where enough monkeys with enough typewriters will eventually produce a Shakespearean sonnet. Of course, it's been proven there's a big bias in even that assumption. However, now, as we learn more about the complexity and intricacy of encoded DNA instruction sets, we are finding out that time is not the friend of evolution.

In a paper published last year in the Journal Theoretical Biology and Medical Modelling, John Sanford, Wesley Brewer, Franzine Smith and John Baumgardner look at the nut and bolts of DNA mutation and calculate just how long it would take to get new, biologically meaningful nucleotides. In other words, we don't simply need genetic mutations. We need mutations that will be of some benefit to the organism, will be significant enough to be "set" in the population, and will be able to do so within a population and generational set projected for the species. Let's look at each of these requirements in more detail.

1. Mutations Must Add to the Fitness of the Organism

In their paper, Sanford et. al. looked at strings of code within the DNA commonly referenced as genes. These strings of code are the instruction set for building all the biological systems that make up you and me. Just as a book is composed sentence by sentence, the sentences are built word by word, and the words are built by strings of letter, so DNA nucleotide strings are the source of the proteins or RNA machines that build more complex biological functions. These are the foundation of biology and it is at this level where any meaningful change must happen for evolution to work.

Further, not just any mutation counts. Just as any recombination or addition of letters doesn't lead to new sentences, the mutations must be to the degree that it provides "stronger fitness benefits" to the organism according to natural selection.1 This isn't controversial in and of itself; common descent argues this way. But needing specific mutations raises the odds and requires more time than just any mutation.

2. Mutations Must be Set Within the Organism

Advantageous mutations are not good enough, though. The mutations must be of a kind to be hereditary. They have to be able to be passed from parent to offspring, otherwise they die with the carrier. Not only do they need to be hereditary but they need to be dominant enough within the population to permeate the species.

Imagine you have an isolated village of blond-haired people. One dark-haired traveler stumbles onto the village and decides to settle there. He marries and has children, some of whom are dark-haired. While dark hair is a dominant trait, not all the dark-haired man's children will necessarily carry his dark hair gene. Dark hair could still be lost within a few generations.

The model used by Sanford et. al. takes this factor into account. It also raises the complexity of the mutation, sometimes requiring the same mutation more than once in a population in order for the gene to be "set."

3. The Size and Reproductive Rate of the Population Matters

Lastly, these kinds of mutations happen at different speeds for different types of organisms, as Michael Behe deftly explained in The Edge of Evolution. For example, the E. Coli bacteria can have a population pool in the millions within a community. It divides every thirty seconds, allowing less than 20 years for researcher Richard Lenski to reach 50,000 generations.2 However, for higher primates, the population size is much smaller and they reproduce at a much slower pace. Human beings must achieve puberty before they can start having babies. This means that mutations are passed much more slowly.

So what happens when you take these various factors and put them all together into a computer model? Just how long is enough time to get a biologically advantageous mutation within a hominid population, that is an animal type that would eventually produce homo sapiens?

Sanford's model shows there simply isn't enough time for enough significant mutations to move from more primitive hominids to human beings. The paper's conclusion states:

Biologically realistic numerical simulations revealed that a population of this type required inordinately long waiting times to establish even the shortest nucleotide strings. To establish a string of two nucleotides required on average 84 million years. To establish a string of five nucleotides required on average 2 billion years. We found that waiting times were reduced by higher mutation rates, stronger fitness benefits, and larger population sizes. However, even using the most generous feasible parameters settings, the waiting time required to establish any specific nucleotide string within this type of population was consistently prohibitive.3 (emphasis added.)

Interestingly, one point noted in the paper was that increasing population sizes to help point number three actually work against point number two by making the new genetic function more diluted within the population group and therefore less likely to become "set."

Overall, the paper is interesting and offers independent verification to the time problem Behe argued in The Edge of Evolution while using a completely different methodology. Make sure you take the time to read it.

Trying to Become More Relevant Makes Liberal Churches Less Relevant

There has been a lot of noise about the rise of the Nones in the U.S. As the 2014 Religious Landscape Study reported, more people are not identifying with any organized religious. That doesn't mean they are all atheists, though. According to the Pew organization that published the study, "the majority of Americans without a religious affiliation say they believe in God. As a group, however, the 'nones' are far less religiously observant than Americans who identify with a specific faith."1 The rise of the Nones mirror the decline in mainline Protestant denominations, while religious groups such as Evangelicals are holding steady or even growing slightly. Millennials are increasingly identifying as Nones.

None of this is surprising. Millennials take an increasingly subjective view of faith claims, just as the more mainline denominations had held and taught. I believe the problem stems from the shift that occurred in the theology of mainline seminaries and churches. In the late 19th and early 20th centuries, mainline denominations became increasingly more theologically liberal, spiritualizing what had previously been understood as objective morality and a record of historic events. This was their fatal move, as Francis Schaeffer pointed out in How Should We Then Live:

The new liberal theology, because it says that the Bible does not touch the cosmos or history, has no real basis for applying the Bible's values in a historic situation, in either morals or law. Everything religious is in the area of non-reason, and since reason has no place there, there is no room for discussion; there are only arbitrary pronouncements. Immanuel Kant could not bring together the noumenal and the phenomenal worlds, and the new theologian has no way logically to bring his personal arbitrary values into a historic situation. Or to say it another way: Sartre said that in an absurd world we can authenticate ourselves by an act of the will; but, as we saw, because reason has no place in this we can help people or hurt them. Similarly, because the pronouncements of these theologians about morals or law are arbitrary, in a different mood they, too, can be totally reversed.

The new theologians also have no way to explain why evil exists, and thus they are left with the same problem the Hindu philosophers have; that is, they must say that finally everything that is is equally in God. In Hindu thought one of the manifestations of God is Kali, a feminine representation of God with fangs and skulls hanging about her neck. Why do Hindus picture God this way? Because to them everything that exists now is a part of what has always been, a part of that which the Hindus would call "God"—and therefore cruelty is equal to non-cruelty. Modern humanistic man in both his secular and his religious forms has come to the same awful place. Both have no final way to say what is right and what is wrong, and no final way to say why one should choose non-cruelty instead of cruelty.2

Because mainline denominations abdicated an objective standard of scripture for subjective one, they lost their claim to any real knowledge about the world. The Millennials have recognized this. If there is nothing liberal theology can provide and concrete and objective, then why bother with it at all? If one teaches an olly-olly-oxen-free approach to faith, then why would anyone need to bother with the inconvenience of waling up early to drive to some church building and sit in a pew so someone else can tell them what their understanding of spirituality is? The congregant has his or her own view, which is equally true, so why not skip the whole enterprise? And that's what they've been doing.

Ironically, many mainline churches have tried to recapture the interest of the Millennial generation by showing just how progressive and accepting of all viewpoints they rare. I see banners all the time hanging from Methodist or ELCA churches proclaiming their diversity and acceptance of views that have historically been anathema in Christianity. They don't seem to realize their stance makes their church less relevant in the mind of Millennials, not more so.

Making the Most of your Daily Devotions (Free Bible Download)

I am in the book of Revelation in my devotions this morning, reading the message of Jesus to the church in Ephesus. Jesus praises the Ephesians for their passionate and diligent pursuit of truth. However, he also warns them they were in danger of losing their place because "You have forsaken the love you had at first." (Rev. 2:4, ESV). This first love seems to be tied to the good deeds they did at the beginning of the church's ministry. Because of this, commentators see the first love to refer both to the love of Jesus and their love for one another.[1]

All Christians need to cultivate and nurture their love of Christ and for others. The first and best discipline to do this is during your daily devotions. As an apologist, my devotion time is critical, as it would be easy to slip into a habit of faith-defending without love. However, a few years ago, I noticed that even my devotions started to become a rote exercise. My prayer time would be dominated by my requests and my reading was all about quickly finishing the chapter so I could move onto something else.

In order to break out of this habit, I decided to be more deliberate in approaching my prayer time. I liked the ACTS outline of prayer (Adoration, Confession, Thanksgiving, and Supplication) but needed a grid in which to place it. So, I came up with the following outline that I keep in my Bible and update monthly. I've created a downloadable template for you to save and use for your own devotion times. You can grab either the PDF or the editable Word version. Fill it in, print it out and keep a folded paper copy in your Bible to use each morning. Then, update it each month.

Here's my approach:

1. Contemplating the Nature of God through the Names of God

In God's word, God reveals different aspects of who he is through the various names he uses for himself. So I took eleven different names of God and laid them out in a two-week grid — one for each weekday and a dual-meaning name for Saturday and Sunday. I then contemplate in my prayers the different ways God fulfills the attributes of the "name of the day."

For example, if I am thinking about "Jehovah Sabbaoth - The Lord of Hosts," I contemplate how my holy God s the God over the armies. He can command legions of angels. He is the one who nothing or no one can overwhelm. I let me mind work on that aspect o God's character and I see if I can find new ways of understanding God as the Lord of hosts. Because this is a two-week cycle, it keeps my thoughts about God fresh and my desire to more keenly understand him.

2. Contemplate the Cross and the Sacrifice of Salvation

Coming to the Cross is hugely important. I think about Jesus and what it meant for him to give his back to the torturers. I think about his taking my sin upon himself. I think as a father with children about the sacrifice the Father made as he gave his beloved son to die so that I may live.

3. Ask for forgiveness of sins.

This is the place where I review and confesses my sins. It may be something big or small, but even a sin of hubris or not trusting should be honestly offered here. Make sure you use the Christian's bar of soap (1 John 1:9)!

4. Give thanks for blessings.

We all have more to be thankful for than what we can imagine. I normally open my eyes during this part of my devotional time, so I can be reminded of the many blessings I do have. When I do devotions outside, this drives me to be thankful for God's creation and the oxygen in my lungs.

5. Pray for self.

Here's where I begin the Supplication area. First, I pray I would reflect Jesus in what I say and what I do and what I think. I want to see others the way Jesus would see them. I then pray of my responsibility as a father, as a Christian witness, and any immediate needs I have.

6. Pray for family members

Next, I list out each immediate family member and pray for then. Usually, I pick four or five areas that I pray for. I always try to make sure I think about how can God change/use myself to be more effective in helping them as opposed to "change this thing I don't like" kinds of prayers. Also, because I update this list monthly, it is god practice to come up to your spouse and your children and ask them "What can pray for for you this month?" This ai a great way to stay in touch with your kids and hear what's critical in their, lives.

7. Pray for ministry/job/household finances, etc.

After I've prayed for people, I thin pray for my job or ministry, any financial issues, any difficulties our family may be facing, and other issues affecting us.

8. Weekly rotating prayer for community

Lastly, I use a one week rotation of specific, focused prayer for the larger community. The breakdown is below and also on the template:

• Mon - Church
• Tues - Martyrs & those suffering
• Wed - Government and elected officials
• Thurs - Apologetics ministries
• Fri - Educational institutions
• Sat/Sun — special requests

This list has helped me in my daily devotional time to really pray better, to draw closer to God and to focus my prayers more specifically. I hope it helps you in your devotional time as well. Let me know of any additions or suggestions you have. I can always learn more.

Book Review: The Fate of the Apostles by Sean McDowell

Since Christianity's inception, it has been common for Christian faith-defenders to offer evidence supporting their belief in the risen Jesus. From Paul's testimony in 1 Corinthians 15, the claim of eyewitnesses to support the resurrection of Christ has been integral to Christianity. Many people point to the fact that Jesus's apostles died without ever recanting their belief in him as evidence of the truthfulness of their testimony.

But is this as strong a piece of evidence as we've been led to believe? How do we know the apostles were actually martyred, and does dying for one's faith prove anything other than loyalty to a belief system? These are the questions Dr. Sean McDowell takes up in his new book The Fate of the Apostles: Examining the Martyrdom Accounts of the Closest Followers of Jesus (Ashgate, 2015). In The Fate of the Apostles, McDowell traces the historical evidence for the deaths of each of the Twelve and offers an objective rubric for weighing the probability of their martyrdoms.

Clarifying What They Died For

Martyrdom is a heady concept. Across the theological spectrum, there are many people who give up their comfort for their beliefs. There are fewer who may subject themselves to pain or abuse because of their faith, and fewer still who die for a religious belief. But all religious traditions can probably point to someone who qualifies as a martyr for their particular faith. So, how to approach the apostles' martyrdom, if they truly were martyred, encompasses the first four chapters of the book. McDowell keenly clarifies his goal is not to show the apostles were steadfast unto death not simply in their refusal to give up Christianity, but they very specifically refused to deny seeing the risen Christ.

This is a key point and one that must be emphasized again and again to detractors who would liken the apostles' fate to suicide bombers or some other modern contrivance. There would be a difference between sincerely holding to the faith in which one was raised and groomed versus the threat of death for testifying you've seen an executed enemy of your childhood faith (and Rome) walking around. McDowell makes the point right off in his book by underscoring the distinction:

The deaths of others for their religious causes in no way undermines the evidential significance of the fate of the apostles. Second, the apostles' willingness to die for their beliefs does not demonstrate the inherent truth of the Christian message, but that the apostles really believed that Jesus had risen from the grave. The apostles could have been mistaken, but their willingness to die as martyrs establishes their unmistakable sincerity.1

Outlining the Fate of Each Apostle

In the book, McDowell spends the first four chapters outlining the nature and understanding of what martyrdom is, how it would have been understood to the first generation of Christians, and how it would fit within their newly forming belief system. He then devotes a chapter to each of the apostles, including Paul and Jesus's brother James. As would be expected, the historical evidence shrinks when lesser-known apostles such as Simon the Zealot or Matthias are considered. Still, McDowell does a great job showing that even with some apostles' fate in question, there is ample evidence of apostles who did in fact die for their testimony of the risen Jesus and there exists not a shred of evidence that any apostle recanted their belief. Given each would have been considered an eyewitness testifying on first-hand knowledge, this is impressive and does the heavy lifting in setting up the historical bedrock that the disciples did have some kind of experience that needs explaining.

Readability

While the book is written and priced for an academic audience (Amazon is offering the hardback at a pricey $118), McDowell's style is open and easily enough read to be handled by a sophisticated high school student. The footnotes throughout offer good support for his claims within the text and his openings and conclusions of each chapter gives the reader a nice, concise guide to the evidence more fully developed between them.

The Fate of the Apostles takes on a historical question that no one else to my knowledge has done in such a complete manner. McDowell has truly done us a favor in his research and publishing, investigating claims that were assumed but not demonstrated in a systematic way. We now have a go-to source that should advance the discussion for the evidence of the resurrection. For anyone interested in church history, apologetics, or the origin of Christianity, I highly recommend this book.
