Titus 2:1-15

To young men, in everything set them an example by doing what is good, teaching show integrity, seriousness and soundness of speech that cannot be condemned.
Teach slave to be subject to their masters in everything, to try to please them, not to talk back to them, show that they can be fully trusted. so that in every way they will make the teaching about God our Savior attractive.
Do not let anyone despise you.
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. Paul has a word for older men and women and younger ones. Titus himself must set the example. Salves must try to please, not answer back or steal from their masters. Those who have trusted in God and found salvation will be eager to do what is good.
Why?
Teach what is in accord with sound doctrine.
To old men and women and to young men has different manner, to yound men set an example by doing what is good, teaching show integrity, seriousness.
Working manner is to be a trustworthy men before boss, make the teaching about God our savior attractive.
How?
Dear Lord, please help me let me show integrity, seriousness, and trustworthy, speech without condemned.
