Here is, I. David’s complaint. We should have thought his soul soaring to heaven; but he says himself, My soul not only rolls in the dust, but cleaves to the dust, which is a complaint either, 1. Of his corruptions, his inclination to the world and the body (both which are dust), and that which follows upon it, a deadness to holy duties. When he would do good evil was present with him. God intimated that Adam was not only mortal, but sinful, when he said, Dust thou art, Gen. 3:19. David’s complaint here is like St. Paul’s of a body of death that he carried about with him. The remainders of in-dwelling corruption are a very grievous burden to a gracious soul. Or, 2. Of his afflictions, either trouble of mind or outward trouble. Without were fightings, within were fears, and both together brought him even to the dust of death (Ps. 22:15), and his soul clave inseparably to it.
II. His petition for relief, and his plea to enforce that petition: “Quicken thou me according to thy word. By thy providence put life into my affairs, by thy grace put life into my affections; cure me of my spiritual deadness and make me lively in my devotion.” Note, When we find ourselves dull we must go to God and beg of him to quicken us; he has an eye to God’s word as a means of quickening (for the words which God speaks, they are spirit and they are life to those that receive them), and as an encouragement to hope that God would quicken him, having promised grace and comfort to all the saints, and to David in particular. God’s word must be our guide and plea in every prayer.
