The quote which Gerstner alluded to in his lecture on TULIP by George Whitefield.

Come, ye dead, Christless, unconverted sinner, come and see the place where they laid the body of the deceased Lazarus; behold him laid out, bound hand and foot with grave clothes, locked up and stinking in a dark cave, with a great stone placed on top of it. View him again and again; go nearer to him; be not afraid; smell him, Ah! how he stinketh. Stop there now, pause a while; and whilst thou art gazing upon the corpse of Lazarus, give me leave to tell thee with great plainness, but greater love, that this dead, bound, entombed, stinking carcass, is but a faint representation of thy poor soul in it natural state;...thy spirit which thou bearest about with thee, sepulchered in flesh and blood, is literally dead to God, and as truly dead in trespasses and sins, as the body of Lazarus was in the cave. Was he bound hand and foot with grave clothes? So art thou bound hand and foot with thy corruptions; and as a stone was laid on the sepulchre, so there is a stone of unbelief upon thy stupid heart. Perhaps thou has lain in this estate, not only four days, but many years, stinking in God's nostrils. And, what is still more effecting, thou art as unable to raise thyself out of this loathsome, dead state, to a life of righteousness and true holiness, as ever Lazarus was to raise himself from the cave in which he lay so long. Thou mayest try the power of thy boasted free will, and the force and energy of moral persuasion and rational arguments (which, without doubt, have their proper place in religion); but all thy efforts, exerted with never so much vigor, will prove quite fruitless and abortive, till that same Jesus, who said; take away the stone" and cried "Lazarus, come forth," also quicken you. This is grace, graciously offered, and grace graciously applied.
