Remedy (2). Seriously to consider, That the giving way to a less sin makes way for the committing of a greater. He that, to avoid a greater sin, will yield to a lesser, ten thousand to one but God in justice will leave that soul to fall into a greater. If we commit one sin to avoid another, it is just we should avoid neither, we having not law nor power in our own hands to keep off sin as we please; and we, by yielding to the lesser, do tempt the tempter to tempt us to the greater. Sin is of an encroaching nature; it creeps on the soul by degrees, step by step, till it hath the soul to the very height of sin. David gives way to his wandering eye, and this led him to those foul sins that caused God to break his bones, and to turn his day into night, and to leave his soul in great darkness. Jacob and Peter, and other saints, have found this true by woful experience, that the yielding to a lesser sin hath been the ushering in of a greater. The little thief will open the door, and make way for the greater, and the little wedge knocked in will make way for the greater. Satan will first draw thee to sit with the drunkard, and then to sip with the drunkard, and then at last to be drunk with the drunkard. He will first draw thee to be unclean in thy thoughts, and then to be unclean in thy looks, and then to be unclean in thy words, and at last to be unclean in thy practices. He will first draw thee to look upon the golden wedge, and then to like the golden wedge, and then to handle the golden wedge, and then at last by wicked ways to gain the golden wedge, though thou runnest the hazard of losing God and thy soul for ever; as you may see in Gehazi, Achan, and Judas, and many in these our days. Sin is never at a stand: Ps. 1:1, first ungodly, then sinners, then scorners. Here they go on from sin to sin, till they come to the top of sin, viz. to sit in the seat of scorners, or as it is in the Septuagint—τῶν λοιμῶν—to affect the honour of the chair of pestilence.
