God doesn't use perfect people or there would be no use for Him.

God doesn't see the imperfections....He only sees the possibilities.

See others the way God sees them.

1 Peter 3:9 Do not repay evil with evil, on the contrary, repay evil with blessings.

Luke 6:39 Love your enemies.

1. Do I really want to be even with them? Even=we are at the same level.
2. What story do you want to tell when it's over?
3. What would it look like to return evil with evil? Return evil with good?
