Albert Barnes Commentary Titus 3:8

"Faithful is the saying, and concerning these things I desire that thou affirm confidently, to the end that they who have believed God may be careful to maintain good works. These things are good and profitable unto men:" — Titus 3:8 (ASV)

This is a faithful saying.

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 you 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 men to holy living. .

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.
