The book of Genesis shows that God put Adam and Eve in the Garden of Eden. They were allowed to eat the fruit of all trees, including the tree of life, but not the tree of the knowledge of good and evil (Genesis 2-3). Eating the fruit of the tree of life represented choosing total reliance on God to show what is good or evil (through His law and Holy Spirit). Eating the fruit of the latter tree represented human beings choosing for themselves what is good and evil, rejecting any direction from God.
