“The grace of the Lord Jesus Christ be with your spirit. Amen.”
Paul, The Apostle of Grace
Paul could have concluded his letter to the Philippians any way he chose...with any words he chose. Yet he chose to end his letter, as he does most of his letters, emphasizing the grace of our Lord Jesus Christ and the Philippian believers experience of grace.
Paul did not choose to close his letter this way because it was a nice way to close the letter. No, he chose to conclude his letter this way because the grace of the Lord Jesus Christ had completely changed his life (1 Corinthians 15:10; 1 Timothy 1:12-17), and his assignment in life was to communicate grace to people (Acts 20:24).
