Charles H. Spurgeon on Psalms 39:13

O spare me, that I may recover strength, before I go hence, and be no more. Man in his corrupt state is like Nebuchadnezzar, he hath a beast's heart, that craves no more than the satisfaction of his sensual appetite; but when renewed by grace, then his understanding returns to him, by which he is enabled in praying for temporals to elevate his desires to a nobler end. Doth David pray that some farther time may be added to his temporal life? It is not out of a fond love for this world, but to prepare himself the better for another. Is he comforted with hopes of a longer stay here? It is not this world's carnal pleasures that kindle this joy in his holy breast, but the advantage that thereby he shall have for praising God in the land of the living...O spare me, that I may recover strength. David was not yet recovered out of that sin which had brought him exceeding low as you may perceive, Ps 39:10-11. And the good man cannot think of dying with any willingness till his heart be in a holier frame: and for the peace of the gospel, serenity of conscience, and inward joy; alas! all unholiness is to it as poison is to the spirits which drink them up. William Gurnall.
