Slef-controlled behave

Titus 2:1-15
Paul has a word for older men and women and younger ones. Titus himself must set the example .
Those who oppose you may be ashamed because they have nothing bad to say about us.
Teach older man, older women and encourage the young men to be self-controlled....
Slaves must try to please, not answer back or steal from their masters.
For the grace of God that brings salvation has appeared to all men. It teaches us to say "No" to ungodliness and worldly passions, and to live self-controlled, upright and godly lives in this present age.
Do not let anyone despise you.
Why?
The way Christians behave can discredit, or reinforce, the Christian message. Paul's instructions throw no flattering light on the Cretan temperament. They were a naturally belligerent, argumentative people, uncontrolled, resentful of authority and partial to the bottle! But the Christian life calls for discipline, obedience and respect for others.
Christian should live like Christ, who is an example to us. Let other respect Christian and like to follow Christ.
How?
Live out the glory of the Lord and let the name of God be exalted. Self-controlled is needed.
