Suppose a company of ugly, uncomely, deformed persons dwelt together in one house; and suppose that they never yet saw any man or woman more than themselves, or that were arrayed with the splendours and perfections of nature; these would not be capable of comparing themselves with any but themselves, and consequently would not be affected and made sorry for their uncomely natural defections. But now bring them out of their cells and holes of darkness, where they have been shut up by themselves, and let them take a view of the splendour and perfections of beauty that are in others, and then, if at all, they will be sorry and dejected at the view of their own defects. This is the case; men by sin are marred, spoiled, corrupted, depraved, but they may dwell by themselves in the dark; they see neither God, nor angels, nor saints, in their excellent nature and beauty: and therefore they are apt to count their own uncomely parts their ornaments and their glory. But now let such, as I said, see God, see saints, or the ornaments of the Holy Ghost, and themselves as they are without them, and then they cannot but must be affected with and sorry for their own deformity. When the Lord Christ put forth but little of his excellency before his servant Peter’s face, it raised up the depravity of Peter’s nature before him to his great confusion and shame; and made him cry out to him in the midst of all his fellows, ‘Depart from me, for I am a sinful man, O Lord’ (Luke 5:4-8).
This therefore is the cause of a broken heart, even a sight of divine excellencies, and a sense that I am a poor, depraved, spoiled defiled wretch; and this sight having broken the heart, begets sorrow in the broken-hearted. —John Bunyan, The Acceptable Sacrifice
