There are few things more relieving than knowing that you’re forgiven, that guilt has been removed, that there is nothing owing. As the line says,
“A good conscience makes a soft pillow.”
There is nothing that allows for freer breathing and a sense of peace than to know that one is right with one’s Maker. What a wonderful thing it is to be surrounded by God’s gentle mercy, to know that He longs to forgive those who have wronged Him. "I take no delight in the death of the wicked. I long for you to turn from your sins and be saved."
I suspect there are few things that make a person more miserable than pretending to not need forgiveness.
