Chapter IV.
The reasons and causes of apostasy from the truth or doctrine of the gospel, and the inclination of all sorts of persons thereunto in all ages, inquired into and declared — Uncured enmity in the minds of many against spiritual things, and the effects of it in a wicked conversation, the first cause of apostasy.
For an entrance into the ensuing discourse, I shall lay down that principle which, I presume, all men will give their assent unto, — namely, that a defection from the truth of the gospel once professed is a sin of the highest guilt, and that which will issue in the most pernicious events. God himself did frequently complain, by his prophets of old, that his people “had forsaken him,” and were gone away from him, — that is, from the doctrine and institutions of his law, the only means of conjunction and communion between him and them, Deut. xxviii. 20; 1 Sam. viii. 8; 2 Chron. xxxiv. 25; Jer. v. 7, 19, xvi. 11. To convince them of their horrible folly and iniquity herein, he demands of them what iniquity they had seen in him, what inequality in his ways, what disappointments they had met withal, that they should grow weary of his laws and worship, so as to relinquish them for such things and ways as would end in their temporal and eternal ruin, Jer. ii. 5, Ezek. xviii. 25: for if there were nothing in them whereof they had cause to complain; if they were all holy, just, and good; if in the observance of them there was great reward; if by them God did them good and not evil all their days, — there was no apology or excuse to be made for their folly and ingratitude. That so it was with them, that their defection from the law and institutions of God was the highest folly and greatest wickedness imaginable, is by all acknowledged: yea, it will be so by them who at the same time are under a greater guilt of the same kind; for the judgments of men are ofttimes so bribed by their present interests, or corrupted by the power of depraved affections, as to justify themselves in worse evils than those which they condemn in others.
But as it was with the people of old, so it is at present with them who decline from the mysteries or renounce the doctrines of the gospel, after they have been received and professed by them, or have done so at any time: yea, their guilt hath greater aggravations than accompanied the idolatrous revolts of the Jews of old; for the gospel is a clearer revelation of God, and much more glorious, than that which was made by the law. There is therefore no reason to be taken from itself why men should desert it, either in its doctrines and precepts or the worship which it doth require. Nothing can be charged on the gospel, nothing on any thing contained in it or produced by it, which should countenance any in a defection from it. It is in itself a blessed emanation from the eternal Fountain of wisdom and truth, and hath more impressions and characters upon it of divine excellencies than the whole creation besides. Neither hath it any proper operations or effects on the souls of men but what are means and causes of deliverance from their original apostasy from God, with all the evil that ensued thereon, which is all that is evil; for the recovery of lost mankind from a state of darkness, bondage, and misery, into that of liberty, light, and peace, the present favour and future enjoyment of God, with order and mutual usefulness in this world whilst they continue therein, is the great and immediate design of the truths of the gospel. Neither is there any thing that is truly good, holy, just, benign, or useful among men, but what is influenced by them and derived from them. Some there have been, indeed, perhaps in all ages, who, pretending unto the liberty of it, have really been servants of corruption, and have turned the grace of God into lasciviousness; and some have charged the principal doctrines of it as those which give men a discharge from a necessity of holy obedience and the utmost use of their own endeavours therein. And there are those who, being given up to sensuality of life, living under the power of darkness, in the pursuit of secular ends, have no other thoughts of it But what the devils in the possessed man had of our Lord Jesus Christ, — that it comes to “torment them before the time.” And there are not wanting some who fear no evil But from the gospel, who suppose that the minds of all men would be serene and peaceable, that all things would be quiet, flourishing, and orderly in the world, if the gospel were out of it; for whatever disturbances men make themselves, in envy, wrath, malice, persecution of others, the guilt and blame of them shall be charged on the gospel itself. And it is notoriously known how a false pretence of some grants made in, and appointments settled by, the gospel, hath been made use of to countenance some sorts of men in the crafty acquisition and violent possession of worldly power, grandeur, and wealth, venting themselves in ambition, cruelty, luxury, and pride of life. But the iniquity and folly of all these abominations, cursed artifices of the father of lies and fountain of malice, shall be, if God will, elsewhere discovered. At present I shall take it for granted that in itself it is a glorious representation of divine wisdom, goodness, grace, and love; neither doth it produce any effects but whereof God is the immediate author, and will be the everlasting rewarder. Wherefore the reasons and causes of apostasy from the part of the gospel under present consideration, — that is, the mysteries and truth of its doctrine, — must be searched for in the minds of them by whom it is forsaken, with the external furtherances that do accompany them.
