_Direct._ XV. When you find that some thoughts of sin and vanity are following you still, for all that you can do, you must not therefore plunge your souls into so much solicitousness, fear, and trouble, as may discourage and distract your mind; but wait on God in the complacential and obediential way of cure. It is the tempter's method to keep sinners utterly careless of their thoughts, and senseless of any sin that is in them, as long as he can; and when that hope faileth him, he will labour to make a humble, obedient soul so sensible of the sin of his thoughts, and so careful about them, as to confound him, and cast him into melancholy, discouragement, and despair; and then he will have no command of his thoughts at all; but they will be as much ungoverned another way, and feed continually upon terror. The end of this temptation is to distract you and confound you. The pretence of the tempter will be contrary to his end: for while he driveth you with terrors to think of nothing else but what you have been or are thinking on, and to make your own thoughts the only or principal matter of your thoughts, he will confound you, and make you undisposed to all good, and unable to govern your thoughts at all. But if you principally study the excellencies of God and godliness, and take the course which tends to make religion pleasant to you, and withal keep up an awful obedience to God, this complacential obedience will best prevail.
_Direct._ XVI. Therefore deliver up your hearts to Christ in love and duty, and consecrate your thoughts entirely to his service, and keep them still exercised on him, or in his work: and this will most effectually cure them of vanity and sin.[301] If you have a friend that you love entirely, you will not feed swine in the room that must entertain him; you will not leave it nasty and unclean; you will not leave it common to every dirty, unsuitable companion, to intrude at pleasure and disturb your friend. So love and pleasure will be readily and composedly careful, to keep clean the heart, and shut out vain and filthy thoughts, and say, This room is for a better guest; nothing shall come here which my Lord abhorreth: is he willing so wonderfully to condescend, as to take up so mean a habitation, and shall I straiten him, or offend him, by letting in his noisome enemies? Will he dwell in my heart, and shall I suffer thoughts of pride, or lust, or malice, to dwell with him, or to enter in? Are these fit companions for the Spirit of grace? Do I delight to grieve him? I know as soon as ever they come in, he will either resist them till he drive them out again, or he will go out himself. And shall I drive away so dear a Friend, for the love of a filthy, pernicious enemy? Or do I delight in war? Would I have a continual combat in my heart? Shall I put the Spirit of Christ to fight for his habitation, against such an ignominious foe? Indeed there is no true cure for sinful, vain, unprofitable thoughts, but by the contrary; by calling up the thoughts unto their proper work, and finding them more profitable employment: and this is by consecrating the heart and them entirely to the love and service of him, that hath by the wonders of his love, and by the strange design of his purchase and merits, so well deserved them. Let Christ come in, and deliver him the key, and pray him to keep thy heart as his own, and he will cast out buyers and sellers from his temple, and will not suffer his house of prayer to be a den of thieves. But if you receive Christ with reserves, and keep up designs for the world and flesh, marvel not if Christ will be no partners with them, but leave all to those guests, which you would not leave for him.
_Tit._ 2. _Directions to furnish the Mind with Good Thoughts._[302]
To have the mind well furnished with matter for holy and profitable thoughts, is necessary to all that have the use of reason, though not to all alike. But I shall here present you only with such materials as are necessary to a holy life, and to be used in our daily walk with God; and not meddle with such as are proper to pastors, magistrates, or other special callings, though I may give some general directions also for students in the end of this.
