Titus 3:8-9

This is a faithful and trustworthy saying; and concerning these things I want you to speak with great confidence, so that those who have believed God [that is, those who have trusted in, relied on, and accepted Christ Jesus as Savior,] will be careful to participate in doing good and honorable things. These things are excellent [in themselves] and profitable for the people. But avoid foolish and ill-informed and stupid controversies and genealogies and dissensions and quarrels about the Law, for they are unprofitable and useless.
