Summary: David starts by describing himself crying out to God continually, yet with no answer; he continues and finishes by proclaiming God's might and power even without a response.
Response: (If you're somehow reading this and haven't heard, this is one of the last seven words of Jesus. Dying on the cross, he starts the psalm, which sounds hopeless to those who don't get it but triumphant to those who know the rest of it.)
David shows humility! Wow! Help me to do the same, Lord, even as I ask for boldness before You.
