1 John 1:9 is a favorite of many people: “If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.” Some have referred to this as the Christian’s bar of soap.

It’s not until you’ve been royally screwed over by someone that you realize how impossible it is to forgive. It’s downright unnatural, like taking a bath with your cat. For Christians, most of us believe it is our obligation and duty to rush headlong into forgiveness the moment we are betrayed, as Jesus modeled for us in the gospels.

The absense of forgiveness may the highest barrier to living and doing business unfettered by the past. Glenn McMahan is convinced forgiveness is a tall obstacle, but he doesn't believe it's insurmountable.
