Now here is something that is not widely known. One of the things the New Testament makes clear is that right now, in the Church Age, people do not have to keep the Sabbath day holy. If you want to honor a day as being holy you are free to do that, and if you don’t then you are free to do that as well. We have the freedom to do as we please (see Romans 14:5-6).
However, in the Millennial Kingdom things will be different. It appears that on the Sabbath, everyone will gather together to worship God. We find this interesting fact at the very end of Isaiah:
Isaiah 66:23: “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.
24 And they shall go forth, and look upon the carcases of the men that have transgressed against me: for their worm shall not die, neither shall their fire be quenched; and they shall be an abhorring unto all flesh.”
The passage is pretty clear. From one new moon to another, and from one Sabbath to another, “all flesh” will come and worship before God. (Just for the record, the Sabbath is a reference to Saturday, not Sunday. In the Church Age we are free to worship on any day that we please, but in the Millennial Kingdom the day of worship will be Saturday.)
Verse 24 is also quite startling. All flesh will gather together to worship God – and all flesh will look upon the tormented souls in Hell, who are tormented day and night forever and ever. In other words, people will worship God and witness His holy judgment. Don’t take my word for it – it’s right there. You can read it for yourself.
It’s just something to think about. We tend to forget that each dispensation has its own set of rules, and that some rules differ from dispensation to dispensation. This is yet another example of that. Before the Church Age men were required to keep the Sabbath holy. During the Church Age men were free to keep any day holy, or keep no day holy. During the Millennial Kingdom men will once again keep the Sabbath day as a day of worship. There are some rules that never change, but there are some rules that do change.
