Titus 2:7-8
In all things shewing thyself a pattern of good works: in doctrine shewing uncorruptness, gravity, sincerity,
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.
Above everything else, exhibit, show in your own life, a pattern of good works; share unadulterated teachings.
Your speech should be in a way that no man can condemn, such that any one who tries to oppose would be put to shame.
