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. Jesus said so .
1 John "For everything in the world—the lust of the flesh, the lust of the eyes, and the pride of life—comes not from the Father but from the world. The world and its desires pass away, but whoever does the will of God lives forever.
