Lord, don’t hold back your tender mercies from me.
    Let your unfailing love and faithfulness always protect me.
¹² For troubles surround me—
    too many to count!
My sins pile up so high
    I can’t see my way out.
They outnumber the hairs on my head.
    I have lost all courage. Psalm 40:11,12

What is the connection between sins and a loss of courage?
