Whenever we come to God with a request, we should remember what David here remembers, that it is only a matter of mercy that God would hear his prayer. David was a great man of God, a “man after God’s own heart,” but even he did not presume to make demands on God but instead cried out for mercy.
And we pray:
I come before You today, O my God, not with any confidence in my own righteousness. But You are the “God of my righteousness,” even as You were to David of old. I come to You in the name of Your Son – Jesus Christ and present my petition before You. I come not as collecting something due to me from You but as one who seeks Your mercy LORD. Father, fill me up in Jesus’ name, Amen.
