Let's see
why God wants Israel to keep the Sabbath...
(Ex. 20:11) For in six days the LORD made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy.
Check: follow God - be holy, for He is holy. He led them out of Egypt, He will lead them into rest. Rest, because He rested. But where did God take them?
Here's a little story:
Ex. 29:36-37 (The consecration of priests) Sacrifice a bull each day as a sin offering to make atonement. Purify the altar by making atonement for it, and anoint it to consecrate it. For seven days make atonement for the altar and consecrate it. Then the altar will be most holy, and whatever touches it will be holy.
Hebrews 2:16-18 For surely it is not angels he helps, but Abraham's descendants. For this reason he had to be made like his brothers in every way, in order that he might become a merciful and faithful high priest in service to God, and that he might make atonement for the sins of the people.
Hebrews 13:10-12 We have an altar from which those who minister at the tabernacle have no right to eat.
The high priest carries the blood of animals into the Most Holy Place as a sin offering, but the bodies are burned outside the camp. And so Jesus also suffered outside the city gate to make the people holy through his own blood.
So Jesus was the sacrifice atoning for our sins; He purified us by his blood. But He was not a substitute, and did not need a substitute himself (Heb. 9:12). God anointed Him with the Holy Spirit (Acts 10:38) as King of Righteousness and High Priest (Heb. 7:11) - and our very own, eternally holy altar. Now he anoints
us (2 Cor. 1:20-22) and makes
us holy. God created the world, we rested with Him on the Sabbath (Jesus spent Saturday in the tomb), and we rise with Him into the first day of the rest of our new lives - which is the day we celebrate.
Once you are born again,
every day is holy,
every day is concecrated to God,
every day bleeds dry on the altar. Of all the commandments, the fourth is the one that comes closest to the first in everyday significance. We're not tempted to murder, lie or steal every day, but every moment we're tempted to forget that we are already have the life God promised Abraham's descendents. The Sabbath was a gift to Israel, and we only understand the full meaning of it now that we have found rest, now that we can get to it without the help of the Law. Jesus
truly kept the Sabbath holy, and we follow Him.
Matthew 23:19-20
You blind men! Which is greater: the gift, or the altar that makes the gift sacred? Therefore, he who swears by the altar swears by it and by everything on it.
God - the true Light - made all of creation pass through this tunnel called "Law", which includes the "shadow" Sabbath. That was to be our
work, our whole duty on earth (Eccles.12:13). His Spirit guided men into it and through it. Christ - the Light of the world - was at the other end. Through Him we found the real Sabbath, the eternal rest.
During his ministry, Jesus emphasized all the commandments in line with their traditional form, except the Sabbath. I think today He would say: "You have heard that it was said to the people long ago, 'Remember the Sabbath day by keeping it holy.' But I tell you that anyone who forgets my rest for even one day, has not kept it."
Hebrews 4:8-10 For if Joshua had given them rest, God would not have spoken later about another day. There remains, then, a Sabbath-rest for the people of God; for anyone who enters God's rest also rests from his own work, just as God did from his.
