Four keys elements in Paul's life kept his joy alive. Constant Thanks v. 3-5 v. 3 Memories . Paul's memories of his time spend in Philippi those ten years ago are all warm and happy. No ill feelings toward those who had beaten him. Whenever you honestly reflect on the blessings God has given you - the result is joy.
Thankful people are happy people.
For some of us our prayer time is a source of pain and difficulty because we pray selfishly. He prays with joy and thanksgiving because of what God had done. As he awaits trial in Rome, Paul spends his time remembering with joy those who stand with him in the faith - NOT focusing on all the hundreds who had done him wrong. We don't see a man eaten up with bitterness, but a man whose heart is overflowing with thanksgiving. Nor should there be obscenity, foolish talk or coarse joking, which are out of place, but rather thanksgiving.
