The message of the letter of the apostle Paul to the people in the church in Philippi (PHILIPPIANS) is about the purpose of life and true happiness. The life of Paul and the purpose of his life teach us the true meaning of happiness. The apostle Paul had a harsh and difficult life, but he never forgot God and always tried to tell the good news about Jesus to others. We should always remember God in our lives – both in tough times or happy times, and ask what he wants us to do. If we live as God wants us to live, we can change ourselves and help people to change.
