Exodus 31.12-17

And the LORD said to Moses, ^“You are to speak to the people of Israel and say, ‘Above all you shall keep my Sabbaths, for this is a sign between me and you throughout your generations, that you may know that I, the LORD, sanctify you. You shall keep the Sabbath, because it is holy for you. Everyone who profanes it shall be put to death. Whoever does any work on it, that soul shall be cut off from among his people. Six days shall work be done, but the seventh day is a Sabbath of solemn rest, holy to the LORD. Whoever does any work on the Sabbath day shall be put to death. Therefore the people of Israel shall keep the Sabbath, observing the Sabbath throughout their generations, as a covenant forever. It is a sign forever between me and the people of Israel that in six days the LORD made heaven and earth, and on the seventh day he rested and was refreshed.’”

As God is working to sanctify us, His people (Phil. 2.13), so we must work to sanctify the Lord’s Day. It is a holy day for us, just as we are a holy people for the Lord. The Lord sets us aside unto Himself in Jesus Christ; then, for the rest of our lives, He works within us to make us willing and able to do His pleasure. He works to sanctify us.

Similarly, we must, in our minds and plans, set the Lord’s Day aside as holy. Then we must work diligently to remember and guard the Lord’s Day, and to fill it with sanctifying works of worship, meditation, and prayer. As we do we are reminded of how the Lord, in the rest we have in Jesus, is working to sanctify us day by day. It’s good to be reminded of this, and the Lord’s Day can “sign” this great work to us, reminding us of it and preparing us for it, week after week.
