Titus 3:8

‘Faithful is the saying, and concerning these things I desire that you affirm confidently, to the end that they who have believed God may be careful to maintain good works. These things are good and profitable to men,’

‘Faithful is the saying’ must look back to the whole of the previous Titus 3:4-7. It is saaying that it is something that is totally unquestionable. Thus Paul wants Titus to affirm it constantly, in order to ensure that all who have savingly believed in God might be careful to maintain good works. Paul knows nothing of a Christian who is not directly involved in going around doing good. And he sums it all up by saying, ‘These things are good and profitable to men’, as they surely are.
