In Genesis 2:17 God tells Adam not to eat from a certain tree.  (Eve did not exist at the time.)  In Chapter 3:1 she is asked a question by a beautiful winged creature, a serpent,  "You can't eat of every tree in the garden?"  Isaiah talks about the flying serpent in Isaiah 14:29 and 30:6.

She answers that they can't eat from the tree and they can't touch it.  Exaggeration.  God said nothing about touching the fruit.  She must have learned about the forbidden tree from Adam--since she didn't exist when God gave his instructions to Adam.

The winged creature then says, "You won't die!"  The devil always lies.  John 8:44 "You are of your father the devil...for he is a liar, and father of it."  He promises something good, and delivers something else.  The father of lies.  We don't take lies seriously enough.  God does.

So she ate the fruit and gave some to Adam--and Adam did what God had personally told him not to do.  Adam knew exactly what he was doing.  The Bible says that Eve was beguiled by this serpent.  He was beautiful and he seemed "in on" some information that she had not heard from her husband Adam.  But Adam heard the restriction on that tree straight from the mouth of God.

Later in Chapter 3:14, 15 and 17, God places curses all three of them because of what they had done. The serpent (winged creature) was cursed with having to crawl around on his belly in the dust from then on.  This is the verse that gives the notion that the serpent that temped Eve was  a snake.  But the Bible doesn't say that.   It says that the serpent became a snake.  The snake was what the serpent was doomed to be after God put a curse on him.  As a point of reference, the word 'snake' is never used.

There is no way Eve would have been temped by a snake.  The serpent is described as "subtle".  He was beautiful.  Isn't that always the case.  Wrap sin up in satin and tie it with a bow and we will open it every time.  That's what is wrong with humans.  Only God can help us.

God help us.
