The Bible is a revelation given by God of Himself, a theology. Since worship is the most definitive feature of every human life, it is critical that we receive this revelation and honour God accordingly. Otherwise, we are worshipping another god. That is idolatry.
The very first theological truth revealed (in the opening chapters of Genesis) is that God is the Creator of all things. This is foundational to all the Bible teaches concerning man's relationship to God. However, because men tend to believe what they wish were true rather than what is, there has been widespread acceptance of the theory of origins known as evolution.
Romans 1:20 exposes the intellectual dishonesty of embracing a belief which denies a Maker while living in the midst of "the things which are made". Man's very constitution as a rational creature means he understands and sees clearly something of the wisdom and power of the one who made the universe. The previous verse tells us that "God hath showed it unto them".
In fact, pure secular evolutionary dogma is so unsatisfying to the human perception that it is gradually morphing into a religious variant that makes god everything and everything god - kind of self creating. The astute observer will immediately recognize this as nothing but pantheism. So evolutionary doctrine has served to deny the God of the Bible, and now opens the door for the reemerging of the ancient Pagan concept of god(s) into Western thought.
Today, under the name of New Age teaching, even professing Christianity is being moved away from the theology and God of the Bible. This concept makes everyone god, or part of god. It distorts the truth historically recognized by Christians that there is a fundamental difference between Creator and creature. It distorts the large body of Bible teaching to do with our accountability to God, and questions the seriousness of sinning against His holy laws.
Saddest of all, for those deceived by it, denial of God's place as Creator also denies the need of salvation through His Son by His sacrifice on the cross. The Christianity of the Bible cannot be mixed with atheistic teachings without eternal loss.
