(1.) If those that have made a great profession of religion throw off their profession, quit the good ways of God and grow loose and carnal, sensual and worldly, the profession they made and all the religious performances with which they had for a great while kept up the credit of their profession shall stand them in no stead, but they shall certainly perish in their iniquity, v. 12, 13, 18. [1.] God says to the righteous man that he shall surely live, v. 13. He says it by his word, by his ministers. He that lives regularly, his own heart tells him, his neighbours tell him, He shall live. Surely such a man as this cannot but be happy. And it is certain, if he proceed and persevere in his righteousness, and if, in order to that, he be upright and sincere in it, if he be really as good as he seems to be, he shall live; he shall continue in the love of God and be for ever happy in that love. [2.] Righteous men, who have very good hopes of themselves and whom others have a very good opinion of, are yet in danger of turning to iniquity by trusting to their righteousness. So the case is put here: If he trust to his own righteousness, and commit iniquity, and come to make a trade of sin—if he not only take a false step, but turn aside into a false way and persist in it. This may possibly be the case of a righteous man, and it is the effect of his trusting to his own righteousness. Note, Many eminent professors have been ruined by a proud conceitedness of themselves and confidence in themselves. He trust to the merit of his own righteousness, and thinks he has already made God so much his debtor that now he may venture to commit iniquity, for he has righteousness enough in stock to make amends for it; he fancies that whatever evil deeds he may do hereafter he can be in no danger from them, having so many good deeds beforehand to counterbalance them. Or, He trust to the strength of his own righteousness, thinks himself now so well established in a course of virtue that he may thrust himself into any temptation and it cannot overcome him, and so by presuming on his own sufficiency he is brought to commit iniquity. By making bold on the confines of sin he is drawn at length into the depths of hell. This ruined the Pharisees; they trusted to themselves that they were righteous, and that their long prayers, and fasting twice in the week, would atone for their devouring widows' houses. [3.] If righteous men turn to iniquity, and return not to their righteousness, they shall certainly perish in their iniquity, and all the righteousness they have formerly done, all their prayers, and all their alms, shall be forgotten. No mention shall be made, no remembrance had, of their good deeds; they shall be overlooked, as if they had never been. The righteousness of the righteous shall not deliver him from the wrath of God, and the curse of the law, in the day of his transgression. When he becomes a traitor and a rebel, and takes up arms against his rightful Sovereign, it will not serve for him to plead in his own defence that formerly he was a loyal subject, and did many good services to the government. No; he shall not be able to live. The remembrance of his former righteousness shall be no satisfaction either to God's justice or his own conscience in the day that he sins, but rather shall, in the estimate of both, highly aggravate the sin and folly of his apostasy. And therefore for his iniquity that he committed he shall die, v. 13. And again (v. 18), He shall even die thereby; and it is owing to himself.
