Titus 1:6; Titus 1:9; Titus 3:8

Titus 1:6

6 An elder must be blameless, faithful to his wife, a man whose children believe and are not open to the charge of being wild and disobedient.

Titus 1:9

9 He must hold firmly to the trustworthy message as it has been taught, so that he can encourage others by sound doctrine and refute those who oppose it.

Titus 3:8

8 This is a trustworthy saying. And I want you to stress these things, so that those who have trusted in God may be careful to devote themselves to doing what is good. These things are excellent and profitable for everyone.
