“The LORD your God is in your midst; he is a warrior who can deliver. He takes great delight in you; he renews you by his love; he shouts for joy over you.”” Zephaniah 3:17 NET http://bible.com/107/zep.3.17.net
Mathew West has a song, 'Forgiveness', that talks about how important it is. It's something that is sorely needed in the world today. Forgiveness does more for the person forgiving than the person being forgiven.
