Introduction: Each Psalm is about an experience in life with God. Psalm 63 was written by King David during one of the most stressful and agonizing "wilderness" experiences of his entire life. Even still, David worships his God. Even still David longs for God more than anything–even the very things that keep him alive like food and water. He remembers his God is better than life. So no matter what He will keep blessing Him as long as he lives. Psalm 63 teaches us to worship in the wilderness.

Summary of David's "wilderness" experience with God (Ps. 63:9-11; 2 Samuel 15-19).

A conscious and conniving effort to remove David from being King was enacted (2 Sam. 15:4-6).
David must flee for his life into the wilderness (2 Sam. 15:12-14, 23).
David does what is right and resolves to let God do whatever he decides is good (2 Sam. 15:24-26).
David refuses to seek revenge or curse in return when slandered, leaving everything in God's hands (2 Sam. 15:28-16:12).

What the wilderness taught David and what it teaches us today.

The wilderness tested David’s resolve to keep God as His God & develop an appetite for Him above all else (v1).
The wilderness taught David to long for & appreciate the “sanctuary” experiences with His God (v2).
The wilderness taught David that God’s love is “better than life” and to bless Him as long as he lives (v3-4).

The wilderness taught David to fight by faith in the future promises of God knowing he will be satisfied (v5-6).
