Let me then, to press this use further upon thee, show thee in a few particulars the danger of not doing of it, that is, of not departing from iniquity, since thou professest.
Danger 1. The iniquity that cleaveth to men that profess, if they cast it not away, but countenance it, will a11 prove nettles and briars to them; and I will assure thee, yea, thou knowest, that nettles and thorns will sting and scratch but ill-favouredly. 'I went,' saith Solomon, 'by the field of the slothful, and by the vineyard of the man void of understanding. And lo, it was all grown over with thorns, and nettles had covered the face thereof, and the stone wall thereof was broken down.' (Prov. 24:30, 31)
Suppose a man were, after work all day, to be turned into a bed of nettles at night: or after a man had been about such a business, should be rewarded with chastisements of briars and thorns: this would for work be but little help, relief, or comfort to him; why this is the reward of a wicked man, of a wicked professor from God; nettles and thorns are to cover over the face of his vineyard, his field, his profession, and that at the last of all; for this covering over the face of his vineyard, with nettles and thorns, is to show what fruit the slovenly, slothful, careless professor, will reap out; of his profession, when reaping time shall come.
Nor can he whose vineyard, whose profession is covered over with these nettles and thorns of iniquity, escape being afflicted with them in his conscience: for look as they cover the face of his vineyard through his sloth now, so will they cover the face of his conscience, in the day of judgment. For profession and conscience cannot be separated long; if a man then shall make profession without conscience of God's honour in his conversation, his profession and conscience will meet in the day of his visitation. Nor will he, whose condition this shall be, be able to ward off the guilt and sting of a slothful and bad conversation, from covering the face of his conscience, by retaining in his profession the name of Jesus Christ: for naming and professing of the name of Christ will, instead of salving such a conscience, put venom, sting, and keenness into those nettles and thorns, that then shall be spread over the face of such consciences. This will be worse than was that cold wet cloth that Hazael took and spread over the face of Benhadad, that he died. (2 Kings 8:15) This will sting worse, tear worse, torment worse, kill worse. Therefore look to it!
Danger 2. Nor may men shift this danger by their own neglect of inquiring into the truth of their separation from iniquity, for that God himself will search them. I search the reins and the heart, saith he, 'to give unto every one of you according to your works.' (Rev. 2:23)
There are many that wear the name of Christ for a cloak, and so make their advantages by their iniquity; but Christ, at death and judgment, will rend this cloak from off such shoulders, then shall they walk naked, yea, the shame of their nakedness shall then appear. Now since no man can escape the search of God, and so, not his judgment; it will be thy wisdom to search thine own ways, and to prevent judgment by judging of thyself.
Danger 3. Christ will deny those to be his that do not depart from iniquity, though they shall name his name among the rest of his people. 'Depart from me,' saith he, 'all you that departed not from iniquity.' (Luke 13:25-27) Yea, they that shall name his name religiously, and not depart from iniquity, are denied by him all along. 1. He alloweth them not now to call him Lord. 'And why call ye me Lord, Lord,' saith he, 'and do not, the things which I say?' (Luke 6:46) He cannot abide to be reputed the Lord of those that presume to profess his name, and do not depart from iniquity. (Ezek. 20:39) The reason is, for that such do but profane his name, and stave others off from falling in love with him and his ways. Hence he says again 'Behold, I have sworn by my great name, saith the Lord, that my name shall no more be named in the mouth of any man of Judah.' (Jer. 44:26; Rom. 2:24) 2. He regardeth not their prayers. 'If I regard iniquity in my heart, the Lord will not hear' my prayer. (Psa. 66:18) And if so, then whatever thou hast at the hand of God, thou hast it, not in mercy, but in judgment, and to work out farther thine everlasting misery. 3. He will not regard their soul, but at the last day will cast it from him, as a thing abhorred by him. As is evidently seen by that thirteenth of Luke, but now noted above.
Wherefore, from these few hints, thou, whoever thou art, mayest well perceive what a horrible thing it is to make a profession of the name of Christ, and not to depart from iniquity. Therefore let me exhort thee again to examine thyself, if thou hast, and dost—since thou professest that name—depart from iniquity.
And here I would distinguish, for there is two parts in iniquity, to wit, the guilt and filth. As for the guilt that is contracted by iniquity, I persuade myself, no man who knows it, needs to be bid to desire to depart from that; nay, I do believe that the worst devil in hell would depart from his guilt, if he could, and might: but this is it, to wit, to depart from the sweet, the pleasure, and profit of iniquity. There are that call evil good, iniquity good, and that of professors too: this is that to be departed from, and these are they that are exhorted to forsake it upon the pains and penalties before threatened. Therefore, as I said, let such look to it, that they examine themselves if they depart from iniquity.
And come, now thou art going about this work, let me help thee in this matter. I. Ask thy heart, What evil dost thou see in sin? II. How sick art thou of sin? III. What means dust thou use to mortify thy sins? IV. How much hast thou been grieved to see others break God's law, and to find temptations in thyself to do it?
