Direct. IX. Remember God's continual presence; that all your thoughts are in his sight. He seeth every filthy thought, and every covetous, and proud, and ambitious thought, and every uncharitable, malicious thought. If you be not atheists, the remembrance of this will somewhat check and control your thoughts, that God beholdeth them. "He understandeth" your "thoughts afar off," Psal. cxxxix. 2. "Doth not he that pondereth the heart consider it," Prov. xxiv. 12. "Wherefore think ye evil in your hearts?" saith Christ, Matt. ix. 4.
Direct. X. Bethink you seriously what a government you would keep upon your thoughts, if they were but written on your foreheads, or seen by all that see you, yea, or but open to some person whom you reverence. Oh how ashamed would you then be, that men should see your filthy thoughts, your malicious thoughts, your covetous and deceiving thoughts! And is not the eye of God ten thousand times more to be reverenced and regarded? And is not man your god, if you are awed more by man than by God, and if the eye of man can do more to restrain you?
Direct. XI. Keep tender your consciences, that they may not be regardless or insensible of the smallest sin. A tender conscience feareth evil and idle thoughts; and will smart in the penitent review of thoughts; but a seared conscience feeleth nothing, except some grievous, crying sins. A tender conscience obeyeth that precept, Prov. xxx. 32, "If thou hast done foolishly in lifting up thyself, or if thou hast thought evil, lay thy hand upon thy mouth."
Direct. XII. Cast out vain and sinful thoughts in the beginning, before they settle themselves and make a dwelling of thy heart. They are easiliest and safeliest resisted in the entrance. Thy heart will give them rooting and grow familiar with them, if they make any stay. Besides, it shows the greater sin, because there is the less resistance, and the more consent. If the will were against them, it would not let them alone so long. Yea, and their continuance tendeth to your ruin; it is like the continuance of poison in your bowels, or fire in your thatch, or a spy in an army: as long as they stay they are working toward your greater mischief. If these flies stay long they will blow and multiply; they will make their nests, and breed their young, and you will quickly have a swarm of sins.
Direct. XIII. Take heed lest any practical error corrupt your understandings; or lest you be engaged in any ill design: for these will command your thoughts into a course of sinful attendance and service to their ends. He that erreth and thinks his sin is his virtue or his duty, will indulge the thoughts of it without control; yea, he will drive on his mind to such cogitations; and steal from the authority and word of God, the motives and incentives of his sin. As false prophets speak against God in the name of God, and against his word as by the pretended authority of his word; so an erring mind will fetch its arguments from God and from the Scripture, for those sinful thoughts which are against God and Scripture. And if evil thoughts will so hardly be kept out when we plead the authority of God and his word against them, and do the best we can to hinder them; how will they prevail when you plead the authority of God and the sacred Scriptures for them, and take it to be your duty to kindle and promote them! For instance; all the sinful thoughts by which the Romish clergy are contriving the support of their kingdom of darkness in the world, and the continuance of their tyranny in the church, are but the products of their error, which tells them that all this should be done, as pleasing to God, and profitable to the church. All the bloody thoughts of persecutors, against the church and holy ways of Christ, have been cherished by this erroneous thought. John xvi. 23, "The time cometh that whoever killeth you, will think that he doth God service; and these things they will do unto you, because they have not known the Father nor me." All Paul's bloody contrivances and practices against the church did come from this. Acts xxvi. 9, "I verily thought with myself, that I ought to do many things contrary to the name of Jesus of Nazareth: which thing I also did." All the scornful and reproachful thoughts and speeches of many of the ungodly against a holy life, are hence: 1 Pet. iv. 4, "They think it strange that you run not with them to excess of riot, speaking evil of you." The vain babbling of hypocrites, who cheat their souls with idle lip-labour, instead of the spiritual service from the heart, and the sacrifice of fools, who offer God some outward thing, while they deny him their hearts and holy obedience, do proceed from this, that "they think to be heard for their much babbling," Matt. vi. 7, "and they consider not that they do evil," Eccl. v. 1. All the self-flattery and presumption of the ungodly, and consequently all their ungodly lives, are much from their erroneous thoughts: "He that thinketh he is something when he is nothing, deceiveth himself," Gal. vi. 3. O come into the light, and forsake your darkness! for sinful thoughts are like hobgoblins and hags, that fly from the light; and like worms and serpents, that creep into holes, and crawl and gender in the dark.
Direct. XIV. Remember what an opening of thoughts there will be, when you come into the light, either here by conviction, or at the furthest at the day of judgment. Then you will be ashamed to see what filth and vanity you entertained; and with what dross and rubbish you stuffed your minds. When the light comes in, what abundance of things will you see to your astonishment, in the dungeon of your hearts, which now you take no notice of! Remember, that all your hidden thoughts must one day be brought into the open light. Say not that this is a thing impossible, because they are so numerous: for God who seeth them all at once, and causeth his sun to illuminate so many millions at once, can make you see them all at once, and yet distinctly, and see the shame and filthiness of every one of them.
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.
