The first humans failed their test of faith. They trusted what they "saw" rather than believing what God said—His words—and became the first example of man choosing to walk by sight rather than by faith. Humanity has followed this example ever since, proving that Adam and Eve's faithlessness was not an aberration but a trait of every human heart, including ours.

What were the consequences of this sin, this act of faithlessness? The answer is in Genesis 3:24: "So He drove out the man; and He placed cherubim at the east of the garden of Eden, and a flaming sword which turned every way, to guard the way to the tree of life."

Adam and Eve's sin of faithlessness destroyed the close relationship they had with God. Because they did not trust Him, their lack of faith put a barrier between themselves and God. The broken trust, faithlessness, ruined that relationship just as it does in our human relationships.

Adam and Eve chose to follow the faithless Satan rather than the faithful God. Satan persuaded them to focus on what they could see rather than what God said. The strategy was so successful that Satan has consistently used it on humanity.

Satan is the prime example of faithlessness. Satan believes God exists, but his is a dead faith because it does not lead to right action. James 2:19-20, from the New Living Translation, forcefully points out the futility and foolishness of Satan's faith: "Do you still think it's enough just to believe that there is one God? Well, even the demons believe this, and they tremble in terror! Fool! When will you ever learn that faith that does not result in good deeds is useless?"
