David began his praise by verbalizing his love for God for being so good to him. He proceeded to describe how much the Lord meant to him by using many metaphors. Yahweh was the source of his strength, stability, safety, and salvation. He was the one in whom David sought refuge, his defense, his power, and his protection. Because God had proved to be such a reliable Savior, the psalmist regarded Him worthy of his praise. [source][source][source]
