John makes a point about the difference between a heart that belongs to God and one that doesn't. The heart that knows God has God and can't help but become more like Him over time. The alternative is a heart that has no place for God and naturally replaces Him with the things that are contrary to Him.

1. Sin means to miss God's nature in action or attitude.

2. A relationship with Jesus makes a big difference in the lives of those who receive it.

3. God hates sin because He knows what it does to those He loves.
