Who can forgive forgiveness where forgiveness is not
Only the lamb as white as snow

John saw Jesus coming toward him and said, "Look, the Lamb of God, who takes away the sin of the world!" John 1:29 NIV

Where might we find the lamb as white as snow?

For you know that it was not with perishable things such as silver and gold that you were redeemed from the empty way of life handed down to you from your ancestors, but with the precious blood of Christ, the lamb without blemish or defect. 1 Peter 1:18-19 NIV

If only a heart could be as white as snow

"Come now, let us settle the matter," says the Lord. "Though your sins are like scarlet, they shall be as white as snow..." Isaiah 1:18 NIV
 
For I know my transgressions, and my sin is always before me.... Cleanse me... and I will be clean; wash me, and I will be whiter than snow. Psalm 51:3-7 NIV
