During and/or after the 1,000 year reign of Jesus, will the Jewish believers still be keeping the Sabbath on Saturday while at the same time the Gentile believers are coming together to worship on Sunday?
During the Tribulation period, we will be back on Jewish territory. 1) Jews are back in the land. 2) a Third Jewish Temple will be rebuilt. 3) Two Old Testament Prophets will come back and testify, Moses and Elijah. 4) Jews will be the witnesses again. 144,000 Jewish witnesses. 5) Blood sacrificies will be offered again. And etc. Gentile believers will again worship as they did in the Old Testament and observe the Sabboth. The Tribulation period is really the LAST SEVEN YEARS OF THE OLD TESTAMENT that have yet to tick off the clock. During the millennium we will observe the Sabboth “And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the LORD.” Also the feast days. See Zechariah 14:16 which says, “And it shall come to pass, that every one that is left of all the nations which came against Jerusalem shall even go up from year to year to worship the King, the LORD of hosts, and to keep the feast of tabernacles. And it shall be, that whoso will not come up of all the families of the earth unto Jerusalem to worship the King, the LORD of hosts, even upon them shall be no rain.” Notice the phrases ‘ALL FLESH’ and ‘ALL NATIONS’!
