By naturalistic, I realize that for the naturalist, everything is within a naturalistic framework. Therefore everything has a naturalistic answer. Even the building of this computer system or the typing of this post is within a naturalistic view. This is why when an evolutionist looks at DNA, he doesn't see the information contained within it in the same manner a creationist does.
For the creationist sees a distinction between things that occur naturally as opposed to things that occur by intelligent design. For a computer system and its software has no natural explanation if we distinguish between and define things that occur naturally as opposed to super-naturally.
Here is the problem for the creationist from the evolutionist perspective. Human beings existence in nature. Therefore we came about by naturalistic means. Chromosomes and DNA do things all by themselves. They are in nature. Therefore they happen naturally.
The response by the creationist is quite simple. Even the naturalist recognizes things that are intelligently designed. When he walks down the street and sees a book on the ground, his first thought is not, "Gee, what a series of accidents." He doesn't even try to justify or rationalize his knowledge that the book has an author. Or perhaps when he is on a nature hike, and he picks up a stone and sees it is designed to be an arrow head. He doesn't think to himself, "Gee, what a series of accidents that formed this arrow head." He just knows the arrow head has a designer.
Therefore, when the creationist says "super-natural", he is simply distinguishing that which has intelligent design, whether it be a computer, car or DNA from that which occurs without intelligent design, such as metal on your car rusting or your computer breaking when it falls to the ground or crystals forming or erosion on a beach.
As the Apostle Paul says in Romans 1
18The wrath of God is being revealed from heaven against all the godlessness and wickedness of men who suppress the truth by their wickedness, 19since what may be known about God is plain to them, because God has made it plain to them. 20For since the creation of the world God's invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse.In conclusion, the creationist is arguing that DNA is violating natural laws. It does things that would only happen if intelligently designed to do so. DNA does not naturally form anymore than a Blog post. It is incumbent upon the naturalist to demonstrate the consistency of his worldview and to demonstrate that everything that happens does so without any intelligent design at all.
They do not live this way in every area of life in which they do not have to actively suppress the truth of God's existence. It is only when their guilt is pressed upon them by the testimony of nature that they become futile in their thinking and hardened in their hearts toward God.
