One question that arises when discussing Intelligent Design vs. the Theory of Evolution, specifically the Creationist variety of I.D. (see discussion on the difference here ) is, “Could God have used evolution?” I think the answer is No, and do not think this is a valid position.
First of all, I do not believe the facts support the Theory of Evolution. Some may say that God is the one who fills in the gaps, so to speak, in the Theory of Evolution. But I don’t think this is valid either. If evolution is true, there is no need for God. And if God exists, then there is no need for evolution. God invading the evolutionary process goes against what the theory itself is postulating, namely that life came into existence by naturalistic and not supernatural means.
Besides the scientific and philosophical reasons against Theistic Evolution, from a Creationist standpoint there are also theological reasons why it cannot be true. As Ken Ham from Answers In Genesis points out, if theistic evolution is true the entire biblical doctrine of sin falls apart. And if the doctrine of sin is dismantled, there is no reason for salvation either, and the gospel falls apart. Darwinism says that death exists as a mode that eliminates organisms and entire species while allows others to adapt and evolve into stronger and fitter creatures. But the Bible says that death didn’t exist until the Fall, and is a direct consequence of that fall into sin. Death exists because sin exists. And because sin and death exist, we need a Savior, the Lord Jesus Christ, to redeem mankind and bring salvation to all who would believe. This has two implications. First, if death existed before sin, the entire gospel can be dismissed. And secondly, if you cannot trust the first chapters of the Bible when it says death is a product of sin, you also cannot trust the Bible when it says you are in need of a Savior. On this count the gospel would also be discredited. But if you can trust Genesis 1:1, you can also trust John 3:16.
For these reasons it is completely unacceptable for someone who claims they believe in the Bible to also put their trust in the Theory of Evolution. I think the Theistic Evolution stance is a cop-out that has been created to try to conform to the world where no compromise is possible.
