Titus 2:1; Titus 2:7-8; Titus 2:15

1 But as for you, teach what accords with sound doctrine.
7 Show yourself in all respects to be a model of good works, and in your teaching show integrity, dignity, 8 and sound speech that cannot be condemned, so that an opponent may be put to shame, having nothing evil to say about us.
15 Declare these things; exhort and rebuke with all authority. Let no one disregard you.
