In context
Before · Titus 3:7–8
7that being justified by his grace, we might be made heirs according to the hope of eternal life. 8This saying is faithful, and concerning these things I desire that you insist confidently, so that those who have believed God may be careful to maintain good works. These things are good and profitable to men;
9but shun foolish questionings, genealogies, strife, and disputes about the law; for they are unprofitable and vain.
