A man must repent before he believes in Christ (Mark i., 15). Now repentance is not a saving grace, having value only as it leads to something further on. The pain of a physical malady has no curative virtue; but it is this pain that inclines the patient to ring the doctor's bell. So John the Baptist goes before Christ with his cry, "Repent ye!" Since without repentance there is no adequate sense of need, nor disposition to accept Christ. Let us get a clear understanding of repentance. It suggests at the outset, an apprehension of sin as a fact; not a figment of the imagination, not "a belief of mortal mind"; not an infection due to environment, and therefore involving no personal accountability; but a distinct, flagrant violation of holy law, by which the sinner is brought into rebellion against God. And sin must be apprehended, furthermore, as a calamitous fact, that is, involving an adequate penalty: "The soul that sinneth, it shall die." A true penitent recognizes the justice of the punishment which is imposed upon him; as did the repentant thief, when he said to his comrade, "We indeed are condemned justly." One who spends his time in trying to explain away hell and "the unquenchable fire" and "the worm that dieth not," is not a penitent man. And sin must be furthermore recognized as a concrete or personal fact. It is not enough to acknowledge the incontrovertible presence of sin in the world around us. The important thing is, that this sin inheres in me. So David prayed, "Have mercy upon me, O God, according unto thy loving kindness; for I have sinned and done this evil in thy sight." He had always known, in general terms, that adultery was a fearful thing; but when it pointed its gaunt finger at him in the watches of the night and hissed, "Bathsheba!" it brought him to his knees. And this conviction of sin must be followed by a resolution to forsake it. The true penitent fears his sin, hates it, loathes it, abhors it, and determines to quit it. But observe, all this is merely preliminary to the one thing needful. There is no virtue in repentance _per se_. The penitent is not saved; he has only discovered his need of salvation. He knows his malady; now how shall he be cured of it? To pause here is death. One in a sinking boat must not be satisfied with stopping the leak; the boat must be baled out. A man head over ears in debt can not recover his credit by resolving to pay cash in the future; he must somehow cancel his past obligations. If a penitent were never to commit another sin, the "handwriting of ordinances" would still be against him. The record of the past remains; and it will confront him in the judgment unless it be disposed of. The past. The mislived past! What shall be done about it? This brings us to the matter in hand: What shall I do to be saved? or How shall I become a Christian?
