About what a believer should do…

Not so with you. Instead, whoever wants to become great among you must be your servant, † and whoever wants to be first must be your slave-- † just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many." † encouraging, comforting and urging you to live lives worthy of God, who calls you into his kingdom and glory. † And we also thank God continually because, when you received the word of God, which you heard from us, you accepted it not as the word of men, but as it actually is, the word of God, which is at work in you who believe. † For you, brothers, became imitators of God's churches in Judea, which are in Christ Jesus: You suffered from your own countrymen the same things those churches suffered from the Jews, † Give the people these instructions, too, so that no one may be open to blame. † If anyone does not provide for his relatives, and especially for his immediate family, he has denied the faith and is worse than an unbeliever. † No widow may be put on the list of widows unless she is over sixty, has been faithful to her husband, † If any woman who is a believer has widows in her family, she should help them and not let the church be burdened with them, so that the church can help those widows who are really in need. † The elders who direct the affairs of the church well are worthy of double honor, especially those whose work is preaching and teaching. †
