Who forgiveth all thine iniquities. Here David begins his list of blessings received, which he rehearses as themes and arguments for praise. He selects a few of the choicest pearls from the casket of divine love, threads them on the string of memory, and hangs them about the neck of gratitude. Pardoned sin is, in our experience, one of the choicest boons of grace, one of the earliest gifts of mercy, —in fact, the needful preparation for enjoying all that follows it. Till iniquity is forgiven, healing, redemption, and satisfaction are unknown blessings. Forgiveness is first in the order of our spiritual experience, and in some respects first in value. The pardon granted is a present one —forgiveth;it is continual, for he still forgiveth;it is divine, for God gives it; it is far reaching, for it removes all our sins; it takes in omissions as well as commissions, for both these are in-equities;and it is most effectual, for it is as real as the healing, and the rest of the mercies with which it is placed. Who healeth all thy diseases. When the cause is gone, namely, iniquity, the effect ceases. Sicknesses of body and soul came into the world by sin, and as sin is eradicated, diseases bodily, mental, and spiritual will vanish, till "the inhabitant shall no more say, I am sick." Many-sided is the character of our heavenly Father, for, having forgiven as a judge, he then cures as a physician. He is all things to us, as our needs call for him, and our infirmities do but reveal him in new characters.
"In him is only good,
In me is only ill,
My ill but draws his goodness forth,
And me he loveth still."
God gives efficacy to medicine for the body, and his grace sanctifies the soul. Spiritually we are daily under his care, and he visits us, as the surgeon does his patient; healing still (for that is the exact word) each malady as it arises. No disease of our soul baffles his skill, he goes on healing all, and he will do so till the last trace of taint has gone from our nature. The two alls of this verse are further reasons for all that is within us praising the Lord. The two blessings of this verse the Psalmist was personally enjoying, he sang not of others but of himself, or rather of his Lord, who was daily forgiving and healing him. He must have known that it was so, or he could not have sung of it. He had no doubt about it, he felt in his soul that it was so, and, therefore, he bade his pardoned and restored soul bless the Lord with all its might.
