This is a faithful saying
Meaning the whole of what is before expressed, concerning the state and condition of God's elect by nature; the appearance of the love and kindness of God to them in the effectual calling; the salvation of them, according to the mercy of God, and not by works of righteousness; regeneration, and renovation by the Spirit of God, in which such an abundance of grace is communicated; and justification by the free grace of God, as God's way of salvation; and by which men are made to appear to be heirs of eternal life, and to have hope of it: now all, and each of this is a faithful saying, is true doctrine, and to be believed, professed, and published: wherefore it follows,
and these things I will that thou affirm constantly;
that is, the above doctrines; the Arabic version renders it, "I will that thou be firm in these things"; and the Syriac and Ethiopic versions, "I will that thou confirmest them": the sense of the apostle is, that he would have Titus be assured of those truths himself; be at a point about them, and without any doubt or hesitation concerning them; and abide firm and constant in them, and speak of them with certainty, boldness, and confidence to others; and endeavour to confirm and establish them in them: for which purpose he would have them be frequently inculcated and insisted on; and that with this further view,
that they which have believed in God might be careful to maintain
for "that", does not design the subject matter of the charge, or what the apostle would have constantly affirmed, but the end, and final event and issue of it; and nothing can more strongly engage to a studious concern for the performance of good works than the frequent insisting upon the above doctrines of grace: "by good works", are meant, not merely honest trades, and the lawful occupations and businesses of life, which should be carefully attended to, and diligently followed, in order to be useful and profitable to themselves, their families, and others; but every good work, every branch of duty, moral, civil, and religious: to "maintain" these according to the signification of the word used, is to excel in them; to outdo others; to go before others, by way of example, and so to provoke to love and to good works; and to make them the employment and business of men's lives; for which there should be a thoughtfulness, a carefulness, a studious concern, especially in those who "have believed in God"; who are regenerated and renewed by the Spirit of God, and are justified by faith in the righteousness of Christ; who believe in him for peace, pardon, righteousness, life, and salvation: these are under great obligations to perform good works; the love of Christ should constrain them to them; and they are the only persons that are capable of doing them well, for they are sanctified, and made meet, and ready for every good work; they are created in Christ Jesus to them; they have the Spirit of Christ in them, and the strength of Christ with them, without which they cannot be performed well; and they have faith in Christ, without which it is impossible to please God.
These things are good and profitable unto men:
which is to be understood not of good works, though these are good in themselves, and profitable to men in their effects; being done among them, and before them, they set them an example of doing good likewise, when evil communications corrupt good manners; and many of them issue in their temporal good, profit, and advantage: but rather the doctrines of the Gospel are here designed, which are before briefly treated of, and are said to be a faithful saying; and which the apostle would have affirmed with, certainty and constancy, in order to engage believers to the performance of good works; and that for this reason, because these doctrines are "good", excellent, valuable, and precious, comparable to gold, silver, and precious stones: the author, matter, end, and use of them are good; they come from God; they are concerning Jesus Christ, and his grace; they contain good tidings of good things; and are exceeding useful to influence faith, hope, love, and a cheerful obedience to the will of God: they are profitable in the hands of the Spirit of God for conviction, conversion, comfort, and edification; for the quickening and enlightening of dead and dark sinners; for the reviving, establishing, and building up of the saints; they are the wholesome words of Christ, and are according to godliness, and are nourishing, when other doctrines eat as a canker: and this sense is confirmed, not only by what goes before, but by what follows after in the next verse; where insipid notions and controversies are opposed unto them, as unprofitable and vain.
