In the book of Philippians, Paul writes to the believers who are in the city of Philippi.
At this time, Paul was in prison again for having shared the gospel of Christ with others.
Paul manages to provide deep and sincere words of encouragement and gratitude for the church in Macedonia, Philippi. Paul appears to act as a pastor, he offers redirection and exhortation to the members. Their compassion and sympathy touches him deeply as they send a representative from their church who stays to assist Paul but becomes sick and almost dies.
2:25 "But I think it is necessary to send back to you Epaphroditus, my brother, fellow worker and fellow soldier, who is also your messenger, whom you sent to take care of my needs. For he longs for all of you and is distressed because you heard he was ill. Indeed he was ill and almost died." In this passage, we can see how caring Paul and the people he ministered to were.
Paul reminds them that they are to work on faith rather than rituals, laws etc., not to say that laws are not to be obeyed.
He reminds them too in 3:4, "If anyone else thinks he has reasons to put confidence in the flesh, I have more: circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, A Hebrew of Hebrews; in regard to the law, a Pharisee, as for zeal, persecuting the church; as for legalistic righteousness, faultless." But he stresses 3:7 "...whatever was to my profit I now consider loss for the sake of Christ. What is more, I consider everything a loss compared to the surpassing greatness of knowing Christ Jesus my Lord..."
Paul further beautifully exhorts in 4:8, "Finally, brother, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable-if anything is excellent or praiseworthy-think about such things. Whatever you have learned or received or heard from me, or seen in me-put it into practice. And the God of peace will be with you."
