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

1 But speak thou the things which become sound doctrine:
7 In all things shewing thyself a pattern of good works: in doctrine shewing uncorruptness, gravity, sincerity, 8 Sound speech, that cannot be condemned; that he that is of the contrary part may be ashamed , having no evil thing to say of you.
15 These things speak , and exhort , and rebuke with all authority. Let no man despise thee.
