As Christians we accept the truth of God's creation. When presented with the theory that man is "evolving" as a species on earth, we are appropriately skeptical. From what we know, man has been devolving since the fall in The Garden. We started out in perfect harmony with God. Walking with Him and in His physical presence. In full and complete fellowship with our Creator. We had the benefit of free will at this moment. God created us so that we could choose our path. So there was Adam, on a daily physical walk with God. Then sin entered The Garden. How would Adam and Eve react to this? Would they put everything at risk to test what God had declared? Sin is always dark, never truthful, and tempts by appealing to self and pride.
"You will not surely die," the serpent said to the woman. "For God knows that when you eat of it your eyes will be opened, and you will be like God, knowing good and evil.
Adam and Eve disobeyed the clearly marked and articulated "DO NOT TOUCH" sign that our Father in Heaven had provided. But that appears not to be the critical factor. As God sought Adam, He knew that Adam had sinned and being a forgiving God allowed Adam to come clean with his sin. Adam did not take accountability for his sin, nor did he seek forgiveness from his Heavenly Father. That was an action driven from the state of sin taking root in Adam's heart. That it appears was the beginning of man's cycle of devolving. While we might have fancy and improving "technology" more than 6000 years later, we do not yet share the same "fully evolved" relationship with God that was present in The Garden. We have devolved!
However, there is a place where the Christian can accommodate the concept of evolution. Not in the Darwinian sense of fish to lizards to birds to monkeys, but in the glorious and amazing evolution that occurs after we are born again and are justified before God. At the moment we are born again, and as we allow the Holy Spirit to enter our hearts, we start an "evolutionary process" called sanctification. This is the Holy Spirit working in us to transform us and make us more like Christ. That process completes on the day that we meet our Lord and Savior when we experience the glory of being in his presence and fully like Him. Now that is a form of evolution that we can rejoice!
