Titus 2:14-15

who [willingly] gave Himself [to be crucified] on our behalf to redeem us and purchase our freedom from all wickedness, and to purify for Himself a chosen and very special people to be His own possession, who are enthusiastic for doing what is good. [Deut 14:2; Ps 130:8; Ezek 37:23] Tell them these things. Encourage and rebuke with full authority. Let no one disregard or despise you [conduct yourself and your teaching so as to command respect].
