Here we see what we may comfort ourselves with, in reference to this, and the little errors and heresies that both infect and infest the church, and do mischief.
I. It may be a great comfort to us that the unbelief of men cannot make the promise of God of no effect. Though the faith of some particular persons be overthrown, yet the foundation of God standeth sure (Ti2 2:19); it is not possible that they should deceive the elect. Or it may be meant of the truth itself, which they impugn. All the attacks which the powers of darkness have made upon the doctrine of Christ cannot shake it; it stands firm, and weathers all the storms which have been raised against it. The prophets and apostles, that is, the doctrines of the Old and New Testament, are still firm; and they have a seal with two mottoes upon it, one on the one side, and the other on the other, as is usual in a broad seal. 1. One expresses our comfort - that the Lord knows those that are his, and those that are not; knows them, that is, he owns them, so knows them that he will never lose them. Though the faith of some be overthrown, yet the Lord is said to know the ways of the righteous, Psa 1:6. None can overthrow the faith of any whom God hath chosen. 2. Another declares our duty - that every one who names the name of Christ must depart from iniquity. Those who would have the comfort of the privilege must make conscience of the duty. If the name of Christ be called upon us, we must depart from iniquity, else he will not own us; he will say in the great day (Mat 7:23), Depart from me, I never knew you, you workers of iniquity. Observe, (1.) Whatever errors are introduced into the church, the foundation of God standeth sure, his purpose can never be defeated. (2.) God hath some in the church who are his and whom he knows to be his. (3.) Professing Christians name the name of Christ, are called by his name, and therefore are bound to depart from iniquity; for Christ gave himself for us, that he might redeem us from all iniquity, Tit 2:14.
II. Another thing that may comfort us is that though there are some whose faith is overthrown, yet there are others who keep their integrity, and hold it fast (Ti2 2:20): In a great house there are not only vessels of gold, etc. The church of Christ is a great house, a well-furnished house: now some of the furniture of this house is of great value, as the plate in a house; some of small value, and put to mean uses, as the vessels of wood and earth; so it is in the church of God. There are some professors of religion that are like the vessels of wood and earth, they are vessels of dishonour. But at the same time all are not vessels of dishonour; there are vessels of gold and silver, vessels of honour, that are sanctified and meet for the Master's use. When we are discouraged by the badness of some, we must encourage ourselves by the consideration of the goodness of others. Now we should see to it that we be vessels of honour: we must purge ourselves from these corrupt opinions, that we may be sanctified for our Master's use. Observe, 1. In the church there are some vessels of honour and some of dishonour; there are some vessels of mercy and other vessels of wrath, Rom 9:22, Rom 9:23. Some dishonour the church by their corrupt opinions and wicked lives; and others honour and credit it by their exemplary conversation. 2. A man must purge himself from these before he can be a vessel of honour, or meet for his Master's use. 3. Every vessel must be fit for its Master's use; every one in the church whom God approves must be devoted to his Master's service and meet for his use. 4. Sanctification in the heart is our preparation for every good work. The tree must be made good, and then the fruit will be good.

If a man therefore purge himself from these - He that takes heed to his ways and to his doctrines, and walks with God, will separate himself, not only from all false doctrine, but from all wicked men, and thus be sanctified and proper to be employed by the Master in every good word and work. The apostle has not made the application of these different similes, and it is very difficult to tell what he means.

If a man therefore purge himself from these,.... That is, if a man clears himself, and keeps himself clear from such men as Hymenaeus and Philetus, who are comparable to wooden and earthen vessels, and are dishonourable ones; if he shuns their defiling company, and polluting principles; if he keeps clear of their heresies, and is not carried away with the errors of these wicked men, and is not drawn aside by them into immoral practices, but stands fast in the faith, and departs from iniquity:

he shall be a vessel unto honour; he will be made manifest, and appear to be a vessel chosen to honour; and will be an honourable member of the church here, and will be honoured by Christ hereafter:

sanctified: he will appear to be one that is set apart by God the Father, and whose sins are purged away by the blood of Christ, and who is sanctified internally by the Spirit of God; for external holiness springs from internal holiness, and is, an evidence of it:

and meet for the master's use: the use and service of Christ, who is the master of the house; either for the ministry of the word, the administration of ordinances, or for some service or another, which he calls him to, and employs him in.

And prepared unto every good work; which an unregenerate man is not; he is to every good work reprobate; he is not capable of performing good works; he is not prepared for them, nor ready at them; but a true believer, one that is regenerated, and sanctified by the Spirit of God, he is created in Christ Jesus unto good works; and has in the performing of them right principles, aims, and ends, as well as a supply of grace, by which he is enabled to do them.

If a man . . . purge himself from these--The Greek expresses "If one (for example, thou, Timothy) purify himself (so as to separate) from among these" (vessels unto dishonor).

sanctified--set apart as wholly consecrated to the Lord.

and meet--Some oldest manuscripts omit "and."

the master's--the Lord's. Paul himself was such a vessel: once one among those of earth, but afterwards he became by grace one of gold.

prepared unto every good work-- (Ti2 3:17; Tit 3:1). Contrast Tit 1:16.
