Titus 3:8

“This is a faithful saying, etc.] 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…”

“Greek, "faithful is the saying." A formula peculiar to the Pastoral Epistles. Here "the saying" is the statement (Tit 3:4-7) as to the gratuitousness of God's gift of salvation. Answering to the "Amen." these things, &c.--Greek, "concerning these things (the truths dwelt on, Tit 3:4-7; not as English Version, what follow), I will that thou affirm (insist) strongly and persistently, in order that they who have believed God (the Greek for 'believed in God' is different, Joh 14:1. 'They who have learnt to credit God' in what He saith) may be careful ('Solicitously sedulous'; diligence is necessary) to maintain (literally, 'to set before themselves so as to sustain') good works." No longer…”

“This is a faithful saying - See the notes at 1 Timothy 1:15. The reference here is to what he had been just saying, meaning that the doctrine which he had stated about the method of salvation was in the highest degree important, and entirely worthy of belief. And these things I will that thou affirm constantly - Make them the constant subject of your preaching. “That they which have believed in God might be careful to maintain good works.” This shows that Paul supposed that the doctrines of the gospel were fitted to lead people to holy living; compare Titus 3:1, and the notes at Philippians 4:8. The “good works” here refer not merely to acts of benevolence and charity, but to all that is…”

“Be careful to excel in good works - Though the apostle does not lay these for the foundation, yet he brings them in at their proper place, and then mentions them, not slightly, but as affairs of great importance. He desires that all believers should be careful - Have their thoughts upon them: use their best contrivance, their utmost endeavours, not barely to practise, but to excel, to be eminent and distinguished in them: because, though they are not the ground of our reconciliation with God, yet they are amiable and honourable to the Christian profession. And profitable to men - Means of increasing the everlasting happiness both of ourselves and others. Titus 3:10”
