This section provides an explanation on the nature and consequence of sin. Sin is described as being deeply ingrained in people's hearts. Sin is not primarily an activity, it is a condition. Sin infects everyone. The essence of sin is being turned against God. The essence of sin is hell itself: rebellion against God. And the consequence of sin is its result: separation from God. The alternative to sin is pictured as a well-watered tree: deep abiding relationship with God.
