Psalm 51:2 Wash me thoroughly from my iniquity, And cleanse me from my sin.
Sin is that dirty blot in our lives which we like to hide from the rest of the world; just as we may try to hide a dirty smudge on our clothes, we try to hide our sin from others.
God can see through any disguise we hold up. God wants to wash us cleaner than we can ourselves.
We may be able to scrape off some things but deep cleansing is God’s domain; he alone can wash us white as snow.
Christ gave His own life, blood, torment and time on the cross so we could be forgiven and brought to Him as clean babes. Trust Him.
