Psalms 63:1

The title tells us when the psalm was penned, when David was in the wilderness of Judah; that is, in the forest of Hareth (Sa1 22:5) or in the wilderness of Ziph, Sa1 23:15. 1. Even in Canaan, though a fruitful land and the people numerous, yet there were wildernesses, places less fruitful and less inhabited than other places. It will be so in the world, in the church, but not in heaven; there it is all city, all paradise, and no desert ground; the wilderness there shall blossom as the rose. 2. The best and dearest of God's saints and servants may sometimes have their lot cast in a wilderness, which speaks them lonely and solitary, desolate and afflicted, wanting, wandering, and unsettled, and quite at a loss what to do with themselves. 3. All the straits and difficulties of a wilderness must not put us out of tune for sacred songs; but even then it is our duty and interest to keep up a cheerful communion with God. There are psalms proper for a wilderness, and we have reason to thank God that it is the wilderness of Judah we are in, not the wilderness of Sin. David, in these verses, stirs up himself to take hold on God, I. By a lively active faith: O God! thou art my God. Note, In all our addresses to God we must eye him as God, and our God, and this will be our comfort in a wilderness-state.
