It Is Well with My Soul

This hymn gets me every time. Particularly this verse:

My sin, oh, the bliss of this glorious thought!
My sin, not in part but the whole,
Is nailed to the cross, and I bear it no more,
Praise the Lord, praise the Lord, O my soul!

Either I sing it louder than anyone in church or I can't get the words out at all because they get me so choked up. I think I love this verse so much because is what I have the hardest time grasping. Probably because when I forgive people, I don't *really* forgive them for a while. Dr. Phil would say I'm a "scorekeeper" because I tend to log people's mistakes in my mind and hold on to them for a long time. I can't believe that with all of the mistakes I've made and continue to make, big and small, that someone actually forgives me totally and completely.
