Philippians has often been called Paul's letter of joy as this letter overflows with joy and thanksgiving. Writing from house arrest in Rome, Paul is thankful for the gift he has received from the church at Philippi and he rejoices in their fellowship in the gospel. In all the circumstances of life, Paul has found the secret of contentment. He shares this with the church and with us today as he tells about his situation in prison.
Not that I speak in regard to need, for I have learned in whatever state I am, to be content: 12 I know how to be abased, and I know how to abound. Everywhere and in all things I have learned both to be full and to be hungry, both to abound and to suffer need. 13 I can do all things through Christ who strengthens me.
Philippians 4: 11-13 (NKJV)
