John Wesley on Genesis 3:22

Behold, the man is become as one of us, to know good and evil - See what he has got, what advantages, by eating forbidden fruit! This is said to humble them, and to bring them to a sense of their sin and folly, that seeing themselves thus wretchedly deceived by following the devil's counsel, they might henceforth pursue the happiness God offers, in the way he prescribes.
