O Lord my God, I cried unto thee, and thou hast healed me. David sent up prayers for himself and for his people when visited with the pestilence. He went at once to head quarters, and not roundabout to fallible means. God is the best physician, even for our bodily infirmities. We do very wickedly and foolishly when we forget God. It was a sin in Asa that he trusted to physicians and not to God. If we must have a physician, let it be so, but still let us go to our God first of all; and, above all, remember that there can be no power to heal in medicine of itself; the healing energy must flow from the divine hand. If our watch is out of order, we take it to the watchmaker; if our body or soul be in an evil plight, let us resort to him who created them, and has unfailing skill to put them in right condition. As for our spiritual diseases, nothing can heal these evils but the touch of the Lord Christ: if we do but touch the hem of his garment, we shall be made whole, while if we embrace all other physicians in our arms, they can do us no service. "O Lord my God." Observe the covenant name which faith uses —"my God." Thrice happy is he who can claim the Lord himself to be his portion. Note how David's faith ascends the scale; he sang "O Lord" in the first verse, but it is "O Lord my God, "in the second. Heavenly heart music is an ascending thing, like the pillars of smoke which rose from the altar of incense. I cried unto thee. I could hardly pray, but I cried; I poured out my soul as a little child pours out its desires. I cried to my God: I knew to whom to cry; I did not cry to my friends, or to any arm of flesh. Hence the sure and satisfactory result —Thou hast healed me. I know it. I am sure of it. I have the evidence of spiritual health within me now: glory be to thy name! Every humble suppliant with God who seeks release from the disease of sin, shall speed as well as the Psalmists did, but those who will not so much as seek a cure, need not wonder if their wounds putrefy and their soul dies.
