Answer (3.) Thou hast encouragement for this expecting act of faith from what God already hath enabled thee to do. Thou canst, if a believer indeed, through mercy say, that sin is not in that strength within thy soul as it was before thy acquaintance with Christ, his word and ways. Though thou art not what thou wouldst be, yet also thou art not what thou hast been. There was a time when sin played rex—king, in thy heart without control. thou didst go to sin as a ship to sea before wind and tide. Thou didst dilate and spread thy affections to receive the gale of temptation. But now the tide is turned, and runs against those motions, though weakly—being but new flood; yet thou findest a secret wrestling with them, and God seasonably succouring thee, so that Satan hath not all his will on thee. Well, here is a sweet beginning, and let me tell thee, this promiseth thee a readiness in God to perfect the victory; yea, God would have thy faith improve this into a confidence for a total deliverance. ‘Moses,’ when he slew the Egyptian, ‘supposed his brethren would have understood,’ by that little hint and essay, ‘how that God by his hand would deliver them,’ Acts 7:25. Oh it is a bad improvement of the succours God gives us, to argue from them to unbelief: ‘He smote the rock, that the waters gushed out, can he give bread also?’ He broke my heart, saith the poor creature, when it was a rock, a flint, and brought me home when I was walking in the pride of my heart against him; but, can he give bread to nourish my weak grace? I am out of Egypt; but can he master those giants in iron chariots that stand betwixt me and Canaan? He helped me in such a temptation; but what shall I do the next bout? Oh, do not grieve a good God with these heart‑aching questions. You have ‘the former rain,’ why should you question ‘the latter?’ Benjamin was a good pawn to make old Jacob willing to go himself to Egypt. The grace which God hath already enriched thee with is a sure pledge that more is coming to it.
Direction 3. The expecting act of faith must produce another—an endeavouring act, to set the soul on work in the confidence of that succour it expects from God. When Jehoshaphat had prayed and stablished his faith on the good word of promise, then he takes the field and marches out under his victorious banner against his enemies, II Chr. 20. Go, Christian, do as he did, and speed as he sped. What David gave in council to his son Solomon, that give I to thee, ‘Arise therefore, and be doing, and the Lord be with thee,’ I Chr. 22:16. That faith which sets thee on work for God against thy sins as his enemies, will undoubtedly set god on work for thee against them as thine. The lepers in the gospel were cured, not sitting still but walking. ‘And it came to pass, that, as they went, they were cleansed,’ Luke 17:14. They met their cure in an act of obedience to Christ’s command. The promiseth saith, ‘Sin shall not have dominion over you;’ the command bids, ‘Mortify your members which are on earth.’ Go thou and make a valiant attempt against thy lusts, upon this word of command, and in doing thy duty thou shalt find the performance of the promise. The reason of so many fruitless among Christians concerning the power of their corruptions lies in one of these two miscarriages —either they endeavour without acting faith on the promise (and such indeed go at their own peril, like those bold men, Num. 14:40, who presumptuously went up the hill to fight the Canaanites, though Moses told them the Lord was not among them, thus slighting the conduct of Moses their leader, as if they needed not his help to the victory; a clear resemblance of those who go in their own strength to resist their corruptions and so fall before them)—or else they pretend to believe, but it is ostiâ fide—an easy faith; their faith doth not set them on a vigorous endeavour. They use faith as an eye but not as a hand; they look for victory to drop from heaven upon their heads, but do not fight to obtain it. This is a mere fiction, a fanciful faith. He that believes God for the event, believes him for the means also. If the patient dare trust the physician for the cure, he dare also follow his prescription in order to it. And therefore, Christian, sit not still, and say thy sin shall fall, but put thyself in array against it. God, who hath promised thee victory calls thee to thy arms and means to use thy own hands in the battle if ever thou gettest it. ‘Get thee up,’ said the Lord to Joshua, ‘wherefore liest thou thus upon thy face,’ Joshua 7:10. God liked the prayer and moan he made very well; but there was something else for him to do besides praying and weeping, before the Amorites could be overcome. And so there is for thee, Christian, with thy faith to do, besides praying and expecting thy lusts down, and that is searching narrowly into thy heart, whether there be not some neglect on thy part, as an Achan, for which thou art so worsted by sin, and fleest before the face of every temptation.
