It is not fear of damning, but fear of sinning, which makes the truly humbled cry out for grace. True, the fear of hell, engendered by the threatenings of the law, doth work in the soul much horror and dismay; but it is not hell appearing exceeding dreadful, but sin becoming exceeding sinful and abominable, which is the effectual work of grace. Any man in his reason would tremble at everlasting burnings, more especially when by his nearness to the grave the heat of hell doth, as it were, scorch him; but it is not every dying man that hates sin—yea, none do so unless the Lord hath had dealings with their souls. Say, then, dost thou hate hell or hate sin most? for, verily, if there were no hell, the real penitent would love sin not one whit the more, and hate evil not one particle the less. Wouldst thou love to have thy sin and heaven too? If thou wouldst, thou hast not a single spark of divine life in thy soul, for one spark would consume thy love to sin. Sin to a sin-sick soul is so desperate an evil that it would scarce be straining the truth to say that a real penitent had rather suffer the pains of hell without his sins than enter the bliss of heaven with them, if such things were possible. Sin, sin, SIN, is the accursed thing which the living soul hateth.
