Philippians is a book of joy. The key verse of the book is Philippians 4:4. In addition, throughout the book, joy is the theme. The Greek word for joy is used 9 times and various related words (with prefixes, etc.) are used approximately another 7 times. So our question is “why joy?” “How joy?” Considering his circumstances, Paul has a remarkable outlook on life. He is under house arrest as he writes this letter. This book helps us to develop some conclusions about joy. Joy is not dependent on our circumstances. Joy is a choice—a choice to receive a gift. It is appropriate that we think about thanksgiving today as we receive the Lord’s Supper. There is always reason to give thanks.
