1. I have kept myself blameless (20-29)

David had two opportunities to kill Saul (1Sa 24:8-13; 26:8-11). He would have been justified in doing so, because Saul was pursuing him like a dog looking for a flea. But Saul was the Lord's anointed, so David did not touch him. David feared God and kept his laws even when he was fleeing for his life. God rewarded him. To the faithful, God shows himself faithful; to the pure he shows himself pure. He saves the humble, but brings the mighty crashing down. God himself kept the lamp of David burning down through the generations to Jesus.

2. God's way and word are flawless (30-50)

When we take refuge in God, he equips us to fight our enemy Satan. He arms us with strength by making our feet like the sure-footed feet of a deer. When one's inner life and actions match like the feet of a deer, God's strength flows in. God promised that Abraham's descendants would possess the gates of their enemies; God kept that promise in David; he keeps it today when his servants conquer the strongholds of the nations of the world with the gospel.

Application: Lord, make my heart pure; make my feet like the feet of the deer. Help me to defeat Satan today.
One Word: The Lord lives; trust him wholly
