Original Sin in the Believer

Original sin, though latent in the soul, and as a spring which runs underground, often breaks forth unexpectedly. Christian, you cannot believe that evil which is in your heart, and which will break forth suddenly, if God should leave you. “Is thy servant a dog that he should do this great thing” (II Kings 8:13)? Hazael could not believe he had such a root of bitterness in his heart, that he should rip up the women with child. Is thy servant a dog? Yes, and worse than a dog, when that original corruption within is stirred up. If one had come to Peter and said, Peter, within a few hours you will deny Christ, he would have said, “Is your servant a dog?” But alas! Peter did not know his own heart, nor how far that corruption within would prevail upon him. The sea may be calm, and look clear; but when the wind blows how it rages and foams! So though now your heart seems good, yet when temptation blows, how may original sin discover itself, making you foam with lust and passion. “A Body of Divinity” pgs. 145-6
