"O Lord, heal me; for my bones are vexed." Here he prays for healing, not merely the mitigation of the ills he endured, but their entire removal, and the curing of the wounds which had arisen therefrom. His bones were "shaken," as the Hebrew has it. His terror had become so great that his very bones shook; not only did his flesh quiver, but the bones, the solid pillars of the house of manhood, were made to tremble. "My bones are shaken." Ah, when the soul has a sense of sin, it is enough to make the bones shake; it is enough to make a man's hair stand up on end to see the flames of hell beneath him, an angry God above him, and danger and doubt surrounding him. Well might he say, "My bones are shaken." Lest, however, we should imagine that it was merely bodily sickness — although bodily sickness might be the outward sign —the Psalmist goes on to say, "My soul is also sore vexed." Soul-trouble is the very soul of trouble. It matters not that the bones shake if the soul be firm, but when the soul itself is also sore vexed this is agony indeed. "But thou, O Lord, how long?" This sentence ends abruptly, for words failed, and grief drowned the little comfort which dawned upon him. The Psalmist had still, however, some hope; but that hope was only in his God. He therefore cries, "O Lord, how long?" The coming of Christ into the soul in his priestly robes of grace is the grand hope of the penitent soul; and, indeed, in some form or other, Christ's appearance is, and ever has been, the hope of the saints.
Calvin's favourite exclamation was, "Domine usquequo" —"O Lord, how long?" Nor could his sharpest pains, during a life of anguish, force from him any other word. Surely this is the cry of the saints under the altar, "O Lord, how long?" And this should be the cry of the saints waiting for the millennial glories, "Why are his chariots so long in coming; Lord, how long?" Those of us who have passed through conviction of sin knew what it was to count our minutes hours, and our hours years, while mercy delayed its coming. We watched for the dawn of grace, as they that watch for the morning. Earnestly did our anxious spirits ask, "O Lord, how long?"
