5May the God of endurance and encouragement grant you to live in such harmony with one another, in accord with Christ Jesus, 6that together you may with one voice glorify the God and Father of our Lord Jesus Christ. Romans 15: 5-6

This the conclusion of a long letter, beginning with sin and misery, followed by explaining the redemption in Christ. As miserable as we may be in ourselves, like the rest of humanity, so great it is to be able to glorify God the Father with one voice. Sunday activity of worship and thanksgiving is an expression of blessing and thanksgiving.
