At the time David scribed Psalms 63, he was struggling; his life was turned upside down. The whole world was out to get him. Everything that could go wrong did gone wrong, but he praised God. Saul was trying to kill him; his son, Absalom was trying to kill him; he was hiding in the wilderness, living in caves with little food or water. Yet David's response was "My lips will praise You." If it is us, we would feel like praise God, we want to cry. David sang "I Will (to) Rejoice" because "You, God, are my God." David feel this joy because he had a relationship with God: beholding God's power and glory; His love is better than life, focused on the steadfast love of God. David's circumstances did not impact his life because his attention was on God. When we focused on God, our future is secured. David worshiped God. Despite our situation, God is still on His throne. We experience this through our worship; a worship that raises us out of our situations, builds up our hearts that seeks God. David composed Psalm 63 to be completely directed toward God: "I'm seeking You." Worship starts in the heart. We should be hungry for God, Earnestly: longing; clinging; seeking; and thirsting for God -- can not last a day without Him. David's whole being longed for God. Without God, he suffered the symptoms of dehydration. The hope of salvation comes from a Heart of Worship. Only then will we be satisfied with rich and fattening food.
