Proverbs 24:29

Do not say, "I will do to him as he has done to me; I will pay the man back for what he has done.

" People will wrong us & our flesh will want some revenge, however, vengeance belongs to the Lord. Our job is to love them, forgive them, & pray for those who hurt us. Walk in the Spirit & trust God to take care of those who hurt you.

This is because your forgiveness releases God to "get em" better than you ever could; plus you taking things into your own hands will only lead you into more pain & then discipline from God.
