'Come now, let us reason together,' says the Lord. 'Though your sins are like scarlet, they shall be as white as snow; though they are red as crimson, they shall be like wool.'
(Isaiah 1:18, New International Version)
Nothing stains quite as sin. It not only leaves a stain in our heart but a residue in our minds. But God's grace is shown in that he doesn't just forgive our sins, he doesn't just forget our sins, he banishes them. They are gone. The stain is removed, the guilt is taken away. We are clean by his grace
