1 Paul and Timotheus, the servants of Jesus Christ, to all the saints in Christ Jesus which are at Philippi, with the bishops and deacons:2 Grace be unto you, and peace, from God our Father, and from the Lord Jesus Christ.
I am planning on going through the book of Philippians next. Here is an introduction in my Bible.
Although Paul was writing from prison, joy is a dominant theme in this letter. The secret of his joy is grounded in his relationship with Christ. People today desperately want to be happy but are tossed and turned by daily successes, failures, and inconveniences. Christians are to be joyful in every circumstance, even when things are going badly, even when we feel like complaining, even when no one else is joyful. Christ still reigns and we still know him, so we can rejoice at all times.
This is a personal letter to the Philippians, not intended for general circulation to all the churches as was the letter to the Ephesians. Paul wanted to thank the believers for helping him when he had a need. He also wanted to tell them why he could be full of joy despite his imprisonment and coming trial. In his uplifting letter, Paul devotes only a small space to correcting the Philippians and warning them about potential problems.
