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

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