(1.) The first is a wanton eye, or an eye that doth secretly affect itself with such objects as are tickling of the heart with the thoughts of immodesty and uncleanness. Isaiah calls this a wanton eye: and Peter an eye full of adultery, that cannot cease from sin (2 Peter 2:14; Isa 3:16). This is that also which Christ calleth an evil eye, and John the lust of the flesh, and of the eyes, and doth defile those who are not very watchful over their own hearts (Mark 7:22; 1 John 2:16). This wanton eye is that which the most holy saints should take heed of, because it is apt to seize upon them also. When Paul bids Timothy beseech the young women to walk as becomes the gospel, he bids him do it with all purity (1 Tim 5:1, 2). As, who should say, Take heed that while thou instructest them to holiness, thou thyself be not corrupted with the lust of thy eye. O how many souls, in the day of God, will curse the day that ever they gave way to a wanton eye!
(2.) The second thing that discovereth one much inclining to the lusts of uncleanness, it is wanton and immodest talk; such as that brazen-faced whore in the 7th of the Proverbs had, or such as they in Peter, who allured 'through the lusts of the flesh, through much wantonness, those that were clean escaped from them who live in error' (2 Peter 2:18). 'Out of the abundance of the heart the mouth speaketh,' wherefore if we be saints, let us take heed, as of our eye, so of our tongue, and let not the lust of uncleanness, or of adultery, be once named among us, 'named among us as becometh saints' (Eph 5:3). Mark, 'Let it not be once named.' This implies, that the lusts of uncleanness are devilishly taking, they will both take the heart with eyes and tongue: 'Let it not be once named among you,' &c.
(3.) Another thing that bespeaks a man or woman inclining to wantonness and uncleanness, it is an adorning themselves in light and wanton apparel. The attire of an harlot is too frequently in our day the attire of professors; a vile thing, and argueth much wantonness and vileness of affections. If those that give way to a wanton eye, wanton words, and immodest apparel, be not whores, &c., in their hearts, I know not what to say. Doth a wanton eye argue shamefacedness? Doth wanton talk argue chastity? And doth immodest apparel, with stretched-out necks, naked breasts, a made speech, and mincing gaits, &c., argue mortification of lusts? If any say, that these things may argue pride as well as carnal lusts; well, but why are they proud? Is it not to trick up the body? And why do they with pride trick up the body, if it be not to provoke both themselves and others to lusts? God knoweth their hearts without their outsides: and we know their hearts by their outsides.
My friends, I am here treating of good works, and persuading you to fly those things that are hindrances to them: wherefore bear with my plainness when I speak against sin. I would strike it through with every word, because else it will strike us through with many sorrows (1 Tim 6:9, 10). I do not treat of good works as if the doing of them would save us, for we are justified by his grace, according to the hope of eternal life; yet our sins and evil works will lay us obnoxious to the judgments both of God and man. He that walketh not uprightly, according to the truth of the gospel, is like to have his peace assaulted often, both by the devil, the law, death, and hell; yea, and is like to have God hide his face from him also, for the iniquity of his covetousness (Isa 57:17).
How can he that carrieth himself basely in the sight of men, think he yet well behaveth himself in the sight of God? And if so dim a light as is in man can justly count thee as a transgressor, how shall thy sins be hid from him whose 'eye-lids try the children of men?' (Psa 11:4).
It is true, faith without works justifies us before God (Rom 3:28; 4:5): yet that faith that is alone, will be found to leave us sinners in the sight both of God and man (James 2:18). And though thou addest nothing to that which saveth thee by what thou canst do, yet thy righteousness may profit the son of man; as also saith the text: but if thou shalt be so careless as to say, What care I for being righteous to profit others? I tell thee, that the love of God is not in thee (Job 35:8; 1 John 3:17; 1 Cor 13:1-3). Walk therefore in God's ways, and do them, for this is your wisdom and your understanding in the sight of the nations, which shall hear of all these statutes, and say, 'This great nation is a wise and understanding people' (Deu 4:6).
THIRD. Observe. Every believer should not only take heed that his works be good, and so for the present do them, but should carefully study to maintain them; that is, to keep in a continual exercise of them.
It is an easier matter to begin to do good, than it is to continue therein; and the reason is, there is not so much of a Christian's cross in the beginning of a work, as there is in a continual, hearty, conscientious practice thereof. Therefore Christians have need, as to be pressed to do good, so to continue the work. Man, by nature, is rather a hearer than a doer, Athenian like, continually listening after some new thing; seeing many things, but observing nothing (Acts 17:20; Isa 42:20). It is observable, that after Christ had divided his hearers into four parts, he condemned three of them for fruitless hearers (Luke 8:5-8). O it is hard continuing believing, continuing loving, continuing resisting all that opposeth; we are subject to be weary of well-doing (Gal 6:9). To pluck out right eyes, to cut off right hands and feet, is no pleasant thing to flesh and blood; and yet none but these shall have the promise of life; because none but these will be found to have the effectual work of God's grace in their souls (Matt 18:8, 9): 'If ye continue in my word, then are you my disciples' INDEED (Matt 24:13; John 8:31). And hence it is, that you find so many IFS in the Scripture about men's happiness; as, 'if children, then heirs;' and 'if ye continue in the faith;' and 'if we hold the beginning of our confidence steadfast unto the end' (Rom 8:17; Col 1:23; Heb 3:14). Not that their continuing in the way of God is the cause of the work being right; but the work being right causeth the continuance therein. As John saith in another place, 'They went out from us, but they were not of us; for if they had been of us, [saith he] they would, no doubt, have continued with us' (1 John 2:19). But I say, where the work of God indeed is savingly begun, even there is flesh, corruption, and the body of death to oppose it. Therefore should Christians take heed, and look that against these opposites they maintain a continual course of good works among men.
Besides, as there is that in our own bowels that opposeth goodness, so there is the tempter, the wicked one, both to animate these lusts, and to join with them in every assault against every appearance of God in our souls. And hence it is, that he is called the devil, the enemy, the destroyer, and him that seeks continually to devour us (1 Peter 5:8), I need say no more but this. He that will walk like a Christian indeed, as he shall find it is requisite that he continue in good works, so his continuing therein will be opposed; if therefore he will continue therein, he must make it his business to study how to oppose those that oppose such a life, that he may continue therein.
FOURTH. Now then to help in this, here fitly comes in the last observation, to wit, That the best way both to provoke ourselves and others to good works, it is to be often affirming to others the doctrine of justification by grace, and to believe it ourselves. 'This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God, might be careful to maintain good works' (Titus 3:8).
