Titus 3:8

This is a faithful saying - Πιστος ὁ λογος· This is the true doctrine; the doctrine that cannot fail.

And these things I will - Και περι τουτων βουλομαι σε διαβεβαιουσθαι· And I will, or desire, thee to maintain earnestly what concerns these points. The things to which the apostle refers are those of which he had just been writing, and may be thus summed up: -

1. The ruined state of man, both in soul and body.

2. The infinite goodness of God which devised his salvation.

3. The manifestation of this goodness, by the incarnation of Jesus Christ.

4. The justification which they who believed received through his blood.

5. The mission of the Holy Spirit, and the purification of the heart by his influence.

6. The hope of the resurrection of the body, and the final glorification of both it and the soul through all eternity.

7. The necessity of obedience to the will of God, and of walking worthy of the vocation wherewith they had been called.

8. And all these points he wills him to press continually on the attention of believers; and to keep constantly in view, that all good comes from God's infinite kindness, by and through Christ Jesus.

They which have believed in God - All Christians; for who can maintain good works but those who have the principle from which good works flow, for without faith it is impossible to please God.

These things are good and profitable - They are good in themselves, and calculated to promote the well-being of men.

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 upright and good - to an honest and holy life.

These things are good and profitable unto men - That is, these doctrines which he had stated were not mere matters of speculation, but they were fitted to promote human happiness, and they should be constantly taught.

3:8 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.
