ye shall be as gods, knowing good and evil

Gen 3:5b ye shall be as gods, knowing good and evil

Being made in the image of God, Adam and Eve were already "like" God.   Appealing to pride, Satan's temptation was that knowledge would enable them to decide good and evil for themselves thereby making them as gods.

Instead of trusting in God's words (the tree of life), they sought knowledge so they could decide good an evil for themselves.

Jesus is the way, the truth, and the life.  There is no other avenue to the Father. (John 14:6)

Gen 3:24b a flaming sword which turned every way, to keep the way of the tree of life.

Eph 6:17b the sword of the Spirit, which is the word of God:

God's word is truth (John 17:17)

Godly wisdom, a wholesome tongue, and the fruit of righteousness is a tree of life (Prov 3:18; Prov 11:30; Prov 15:4)
