<p>2:15 <i>These things speak and exhort and reprove with all authority- </i>The authority was the Spirit-guided word of Paul in the letter to Titus. The &quot;things&quot; refer to the wonderful message of salvation by grace, and transformation in response to it. These things were what should be taught from the platform, and not Judaistic legalism. And they were to be a comfort to the hearers the idea of 'exhort'.</p><p><i>Let no one despise your teaching- </i>See on 1 Tim. 4:12 <i>Let no man despise your youth</i>. People did despise the teaching; but we allow others to despise us. It is our choice whether we allow them to despise us. The Judaists would have mocked the message of salvation from sin by grace; they were arguing for purification by ritualistic obedience rather than by the Lord's work in our hearts by the Spirit. But Titus was to be unashamed of the message.</p>
