Titus 3:8

5 not by works [done] in righteousness, which we did ourselves, but according to his mercy he saved us, through the washing of regeneration and renewing of the Holy Spirit,

6 which he poured out upon us richly, through Jesus Christ our Saviour;

7 that, being justified by his grace, we might be made heirs according to the hope of eternal life.

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:

9 but shun foolish questionings, and genealogies, and strifes, and fightings about law; for they are unprofitable and vain.

10 A factious man after a first and second admonition refuse;

11 knowing that such a one is perverted, and sinneth, being self-condemned.
