The Duty of Prayer Inferred from the Helplessness of Man, pp 16-18.
Man is not only a sinful, he is also a helpless, and therefore a dependent being. This offers new and powerful motives for the necessity of prayer, the necessity of looking continually to a higher power, to a better strength than our own. If that power sustain us not, we fall; if he direct us not, we wander. His guidance is not only perfect freedom, but perfect safety. Our greatest danger begins from the moment we imagine we are able to go alone.
The self-sufficiency of man arising from his imaginary dignity, is a favourite doctrine with the nominal Christian. He feeds his pride with this pernicious aliment. And, as we hear much, so we hear falsely, of the dignity of human nature. Prayer, founded on the true principles of Scripture, alone teaches us wherein our true dignity consists. The dignity of a fallen creature is a perfect anomaly. True dignity, contrary to the common opinion, that it is an inherent excellence, is actually a sense of the want of it; it consists not in our valuing ourselves, but in a continual feeling of our dependence upon God, and an unceasing aim at conformity to his image.
Nothing but a humbling sense of the sinfulness of our nature, of our practised offences, of our utter helplessness, and constant dependence, can bring us to fervent and persevering prayer. How did the faith of the saints of old flourish under a darker dispensation, through all the clouds and ignorance which obscured their views of God! "They looked unto him, and were enlightened!" How do their slender means and high attainments reproach us!
David found that the strength and spirit of nature which had enabled him to resist the lion and the bear, did not enable him to resist his outward temptations, nor to conquer his inward corruptions. He therefore prayed, not only for deliverance "from blood-guiltiness," for a grievously remember sin, he prayed for the principle of piety, for the fountain of holiness, the "the creation of a clean heart," for "the renewing of a right spirit," for "truth in the inward parts," that the "comfort of God's help might be granted him." This uniform avowal of the secret workings of sin, this uniform dependence on the mercy of God to pardon, and the grace of God to assist, render his precatory addresses, though they are those of a sovereign and a warrior, so universally applicable to the case of every private Christian.
