I don't want to pick on this specific comment, but I have heard similar objections from within the church before. Within the comment are two common assumptions that evangelical Christians voice, both of which I believe are mistaken. I will tackle some others in later posts, but the first unwarranted assumption is that science is not effective or it isn't somehow appropriate when trying to lead others to Jesus.
Science Properly Done Leads to GodIt has become a common trope that science and reason are tools of the world and Spiritual things cannot be discovered through them. But the church hasn't always held such a view. In fact, the myth that science and reason sit on one side of a divide while faith and belief sit on the other is perpetuated by those who are desperately trying to divorce God from His reality. Historically, modern science was founded and advanced by Christians who were, in the words of Johannes Kepler, "thinking God's thoughts after Him."1
These scientists took passages like Psalm 19:1-4 seriously, in which the Psalmist declares:
The heavens declare the glory of God, and the sky above proclaims his handiwork. Day to day pours out speech, and night to night reveals knowledge. There is no speech, nor are there words, whose voice is not heard. Their voice goes out through all the earth, and their words to the end of the world. (ESV)They believed that they were pursuing the knowledge that God had woven into the fabric of his creation. This is also why Paul points to the understanding of the created order in Romans 1 as God's testimony of himself that holds them accountable:
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. (Romans 1:18-20, ESV).
God Commanded Us to Explore His WorldGod wants us to explore the world he created. Even before Adam's fall, the Bible tells us that God placed him in the garden in order to "to work it and keep it" (Gen 2:15). Such a command would require investigation on Adam's part to understand how the world works, how the plants grow, and how to keep them appropriately.
Augustine even encouraged the Christian to not ignore science as it could damage the Christian's witness. In his commentary on Genesis, Augustine writes:
Usually, even a non-Christian knows something about the earth, the heavens, and the other elements of this world, about the motion and orbit of the stars and even their size and relative positions, about the predictable eclipses of the sun and moon, the cycles of the years and the seasons, about the kinds of animals, shrubs, stones, and so forth, and this knowledge he holds to as being certain from reason and experience. Now, it is a disgraceful and dangerous thing for an infidel to hear a Christian, presumably giving the meaning of Holy Scripture, talking non-sense on these topics; and we should take all means to prevent such an embarrassing situation, in which people show up vast ignorance in a Christian and laugh it to scorn. The shame is not so much that an ignorant individual is derided, but that people outside the household of the faith think our sacred writers held such opinions, and, to the great loss of those for whose salvation we toil, the writers of our Scripture are criticized and rejected as unlearned men. If they find a Christian mistaken in a field which they themselves know well and hear him maintaining his foolish opinions about our books, how are they going to believe those books in matters concerning the resurrection of the dead, the hope of eternal life, and the kingdom of heaven, when they think their pages are full of falsehoods on facts which they themselves have learnt from experience and the light of reason? Reckless and incompetent expounders of holy Scripture bring untold trouble and sorrow on their wiser brethren when they are caught in one of their mischievous false opinions and are taken to task by those who are not bound by the authority of our sacred books. For then, to defend their utterly foolish and obviously untrue statements, they will try to call upon Holy Scripture for proof and even recite from memory many passages which they think support their position, although "they understand neither what they say nor the things about which they make assertion."2If science is done properly, it doesn't lead people away from God. Rather, it should point people to the clear conclusion that the world has a designer. That's the argument that Paul makes in Romans 1 and it is the reason why atheists such as Antony Flew changed his mind and believed that God existed. Of course, people can hold biases and presuppositions that rule out God, and we should recognize that. Science alone isn't the answer. But it shouldn't be discounted as one tool in God's toolbox for declaring himself to a lost world.
