We have here, I. The design of the apostle in writing this epistle to the lately converted Jews and Gentiles; namely, to establish them in the Christian faith, and a practice and conversation truly consonant and conformable thereunto, and in an open and bold profession thereof, especially in times of notorious opposition, whether by artful seduction or violent and inhuman persecution. But then we must see to it very carefully that it be really the Christian faith that we believe, profess, propagate, and contend for; not the discriminating badges of this or the other party, not any thing of later date than the inspired writings of the holy evangelists and apostles. Here observe, 1. The gospel salvation is a common salvation, that is, in a most sincere offer and tender of it to all mankind to whom the notice of it reaches: for so the commission runs (Mark 16:15, 16), Go you into all the world, and preach the gospel to every creature, etc. Surely God means as he speaks; he does not delude us with vain words, whatever men do; and therefore none are excluded from the benefit of these gracious offers and invitations, but those who obstinately, impenitently, finally exclude themselves. Whoever will may come and drink of the water of life freely, Rev. 22:17. The application of it is made to all believers, and only to such; it is made to the weak as well as to the strong. Let none discourage themselves on the account of hidden decrees which they can know little of, and with which they have nothing to do. God’s decrees are dark, his covenants are plain. “All good Christians meet in Christ the common head, are actuated by one and the same Spirit, are guided by one rule, meet here at one throne of grace, and hope shortly to meet in one common inheritance,” a glorious one to be sure, but what or how glorious we cannot, nor at present need to know; but such it will be as vastly to exceed all our present hopes and expectations. 2. This common salvation is the subject-matter of the faith of all the saints. The doctrine of it is what they all most heartily consent to; they esteem it as a faithful saying, and worthy of all acceptation, 1 Tim. 1:15. It is the faith once, or at once, once for all, delivered to the saints, to which nothing can be added, from which nothing may be detracted, in which nothing more nor less should be altered. Here let us abide; here we are safe; if we stir a step further, we are in danger of being either entangled or seduced. 3. The apostles and evangelists all wrote to us of this common salvation. This cannot be doubted by those who have carefully read their writings. It is strange that any should think they wrote chiefly to maintain particular schemes and opinions, especially such as they never did nor could think of. It is enough that they have fully declared to us, by inspiration of the Holy Ghost, all that is necessary for every one to believe and do, in order to obtain a personal interest in the common salvation. 4. Those who preach or write of the common salvation should give all diligence to do it well: they should not allow themselves to offer to God or his people that which costs them nothing, or next to nothing, little or no pains or thought, 2 Sam. 24:24. This were to treat God irreverently, and man unjustly. The apostle (though inspired) gave all diligence to write of the common salvation. What then will become of those who (though uninspired) give no diligence, or next to none, but say to the people (even in the name of God) quicquid in buccam venerit—whatever comes next, who, so that they use scripture-words, care not how they interpret or apply them? Those who speak of sacred things ought always to speak of them with the greatest reverence, care, and diligence. 5. Those who have received the doctrine of this common salvation must contend earnestly for it. Earnestly, not furiously. Those who strive for the Christian faith, or in the Christian course, must strive lawfully, or they lose their labour, and run great hazard of losing their crown, 2 Tim. 2:5. The wrath of man worketh not the righteousness of God, Jas. 1:20. Lying for the truth is bad, and scolding for it is not much better. Observe, Those who have received the truth must contend for it. But how? As the apostles did; by suffering patiently and courageously for it, not by making others suffer if they will not presently embrace every notion that we are pleased (proved or unproved) to call faith, or fundamental. We must not suffer ourselves to be robbed of any essential article of Christian faith, by the cunning craftiness or specious plausible pretences of any who lie in wait to deceive, Eph. 4:14. The apostle Paul tells us he preached the gospel (mind it was the gospel) with much contention (1 Thess. 2:2), that is (as I understand it), with earnestness, with a hearty zeal, and a great concern for the success of what he preached. But, if we will understand contention in the common acceptation of the word, we must impartially consider with whom the apostle contended, and how, the enlarging on which would not be proper for this place.
II. The occasion the apostle had to write to this purport. As evil manners give rise to good laws, so dangerous errors often give just occasion to the proper defence of important truths. Here observe, 1. Ungodly men are the great enemies of the faith of Christ and the peace of the church. Those who deny or corrupt the one, and disturb the other, are here expressly styled ungodly men. We might have truth with peace (a most desirable thing) were there none (ministers or private Christians) in our particular churches and congregations but truly godly men—a blessing scarcely to be looked or hoped for on this side heaven. Ungodly men raise scruples, merely to advance and promote their own selfish, ambitious, and covetous ends. This has been the plague of the church in all past ages, and I am afraid no age is, or will be, wholly free from such men and such practices as long as time shall last. Observe, Nothing cuts us off from the church but that which cuts us off from Christ; namely, reigning infidelity and ungodliness. We must abhor the thought of branding particular parties or persons with this character, especially of doing it without the least proof, or, as it too often happens, the least shadow of it. Those are ungodly men who live without God in the world, who have no regard to God and conscience. Those are to be dreaded and consequently to be avoided, not only who are wicked by sins of commission, but also who are ungodly by sins of omission, who, for example, restrain prayer before God, who dare not reprove a rich man, when it is the duty of their place so to do, for fear of losing his favour and the advantage they promise themselves therefrom, who do the work of the Lord negligently, etc. 2. Those are the worst of ungodly men who turn the grace of God into lasciviousness, who take encouragement to sin more boldly because the grace of God has abounded, and still abounds, so wonderfully, who are hardened in their impieties by the extent and fulness of gospel grace, the design of which is to reduce men from sin, and bring them unto God. Thus therefore to wax wanton under so great grace, and turn it into an occasion of working all uncleanness with greediness, and hardening ourselves in such a course by that very grace which is the last and most forcible means to reclaim us from it, is to render ourselves the vilest, the worst, and most hopeless of sinners. 3. Those who turn the grace of God into lasciviousness do in effect deny the Lord God, and our Lord Jesus Christ; that is, they deny both natural and revealed religion. They strike at the foundation of natural religion, for they deny the only Lord God; and they overturn all the frame of revealed religion, for they deny the Lord Jesus Christ. Now his great design in establishing revealed religion in the world was to bring us unto God. To deny revealed religion is virtually to overturn natural religion, for they stand or fall together, and they mutually yield light and force to each other. Would to God our modern deists, who live in the midst of gospel light, would seriously consider this, and cautiously, diligently, and impartially examine what it is that hinders their receiving the gospel, while they profess themselves fully persuaded of all the principles and duties of natural religion! Never to tallies answered more exactly to each other than these do, so that it seems absurd to receive the one and reject the other. One would think it were the fairer way to receive both or reject both; though perhaps the more plausible method, especially in this age, is to act the part they do. 4. Those who turn the grace of God into lasciviousness are ordained unto condemnation. They sin against the last, the greatest, and most perfect remedy; and so are without excuse. Those who thus sin must needs die of their wounds, of their disease, are of old ordained to this condemnation, whatever that expression means. But what if our translators had thought fit to have rendered the words palai progegrammenoi—of old fore-written of, as persons who would through their own sin and folly become the proper subjects of this condemnation, where had the harm been? Plain Christians had not been troubled with dark, doubtful, and perplexing thoughts about reprobation, which the strongest heads cannot enter far into, can indeed bear but little of, without much loss and damage. Isa. it not enough that early notice was given by inspired writers that such seducers and wicked men should arise in later times, and that every one, being fore-warned of, should be fore-armed against them? 5. We ought to contend earnestly for the faith, in opposition to those who would corrupt or deprave it, such as have crept in unawares: a wretched character, to be sure, but often very ill applied by weak and ignorant people, and even by those who themselves creep in unawares, who think their ipse dixit should stand for a law to all their followers and admirers. Surely faithful humble ministers are helpers of their people’s joy, peace, and comfort; not lords of their faith! Whoever may attempt to corrupt the faith, we ought to contend earnestly against them. The more busy and crafty the instruments and agents of Satan are, to rob us of the truth, the more solicitous should we be to hold it fast, always provided we be very sure that we fasten no wrong or injurious characters on persons, parties, or sentiments.
III. The fair warning which the apostle, in Christ’s name, gives to those who, having professed his holy religion, do afterwards desert and prove false to it, Jude 1:5-7. We have here a recital of the former judgments of God upon sinners, with design to awaken and terrify those to whom warning is given in this epistle. Observe, The judgments of God are often denounced and executed in terrorem—for warning to others, rather than from immediate or particular displeasure against the offenders themselves; not that God is not displeased with them, but perhaps not more with them than with others who, at least for the present, escape. I will put you in remembrance. What we already know we still need to be put in remembrance of. Therefore there will always be need and use of a standing stated ministry in the Christian church, though all the doctrines of faith, the essentials, are so plainly revealed in express words, or by the most near, plain, and immediate consequence, that he who runs may read and understand them. There wants no infallible interpreter, really or conceitedly such, for any such end or purpose. Some people (weakly enough) suggest, “If the scriptures do so plainly contain all that is necessary to salvation, what need or use can there be of a standing ministry? Why may we not content ourselves with staying at home, and reading our Bibles?” The inspired apostle has here fully, though not wholly, answered this objection. Preaching is not designed to teach us something new in every sermon, somewhat that we knew nothing of before; but to put us in remembrance, to call to mind things forgotten, to affect our passions, and engage and fix our resolutions, that our lives may be answerable to our faith. Though you know these things, yet you still need to know them better. There are many things which we have known which yet we have unhappily forgotten. Isa. it of no use or service to be put afresh in remembrance of them?
Now what are these things which we Christians need to be put in remembrance of?
