If you are able to decide what day God declared the Sabbath, then soon we are following the whims of man and not the commands of God. The traditions of men angered our Lord and was a real sticking point with Jesus. Calling someone Lord or King is easy, but I can't imaging standing before my King and telling him we decided to change the Sabbath. This isn't a democracy where we get a vote.
Amen! Jesus is Lord of the Sabbath. The Sabbath is his Day of Victory and therefore is “The Lord’s Day” BECAUSE He rose from the dead “In the Sabbath” Mt28:1 -— What fitting start for the new creation in God which Jesus has given us! Amen!
