From the earliest days of human existence the enemy has enticed men and women away from their Creator by challenging His truthfulness. It is the serpent sowing the seeds of doubt and rebellion the mind of Eve by his insidious question, "Hath God said?" Today the challenge is still being issued. Sadly the challenge often comes from within the body of Christ.
In his book The Christ of the Prophets O. Palmer Robertson writes:
But immediately upon man's creation in innocency, the serpent introduced the first lie that contradicted the truth of God (Gen. 3:1, 4-5). From that point on, the voice of the speaking serpent resonated in the utterances of the false prophets.
If the intent of Satan is to oppose the purposes of God with respect to the redemption of his people, then it is understandable that he would seek to misrepresent the truth in a way that would contradict the revelation given through the Lord's prophets.
By this method he would strike at the root of the means by which God had determined to direct the faith and life of his people. (p. 92)
Of course all of this is moot if Adam and Eve, the garden, and the fall are nothing more than Ancient Near Eastern myths erroneously included in an already error filled Bible.
