The Lord’s Day is a feast day, not a fast day, and this is because God gave Himself to us in the Lord’s Supper to be eaten on His day.
No matter what sort of trial we are facing, what sort of fast the Lord has us in, it’s broken up by this meal. This is because feasting, fellowship, joy, consolation, victory and rest are normative in the Christian life. Conflict, affliction, doubt, trial and sorrow are temporary. God blesses us in and through them, but they are overcome.
This is God’s immovable feast, kicking off every week, given to fill you up, God’s people, with love, assurance and strength. Receive that here from Him, and fill this day full of rest, food, and fellowship. This is the day that the Lord has made, let us rejoice and be glad in it.
