O Lord, the house of my soul is narrow: enlarge it that thou mayest enter in. It is ruinous, O repair it! It displeases thy sight; I confess it, I know. But who shall cleanse it, or to whom shall I cry but unto thee? Cleanse me from my secret faults, O Lord, and spare they servant from strange sins.
-- St. Augustine

This prayer of St. Augustine is awesome! Though our soul displeases God at times, he is the only one who can cleans it and make us acceptable. That's what he does too. What great mercy! What great love! God's love for us is greater than his wrath for our sin. He will cleanse us if we ask.
