live lives worthy of God

2 Thessalonians 2:9-16
We dealt with each of you as a father deals with his own children, encouraging, comforting and urging you to live lives worthy of God, who calls you into his kingdom and glory. --This is a shepherd of God serve altitude.
Paul also thank God because they received the word of God, which they heard from Paul's team, they accepted it not as the word of men, but as it actually is, the word of God.
They became imitators of God's churches in Judea.
Why?
The conventions of the patronage system would have put him under obligation to them and required him to do as they told him. Obviously Paul would want to avoid that and perhaps even more - the odium of itinerant preacher who would say almost anything to ear a living.
Paul is a example of a apostle and good shepherd as Jesus love his sheep.
How?
Take care the sheep whom the Lord gives us with love and encourage them, teaching them to live lives worthy of God.
