1. You're right they didn't understand it. Over the centuries, Israel had lost the knowledge and understanding on how to keep the sabbath , as originally commanded by God at Sinai (see post 107). Christ came and set the example on how to properly observe it which the religious leaders rejected.
2. Then why did Paul make the Gentiles wait until the following sabbath to preach to them the gospel which they most desperately wanted to hear? (Acts 13:14-15, 42-44) or why did Paul work during the week and preach in the synagogue every Sabbath [not everyday] for 18 months in Corinth?? (Acts 18:1-11)
Additionally, the sabbath command was for a specific period of time which was to be kept holy--set apart for sacred use and here's
why
3. There is plenty of scriptural evidence supporting the fact Paul kept the sabbath and in this verse he places the nail on the coffin, sort of speak, confirming its observance by Christians today. Could it be any more obvious??
4. That's quite the twist, Pegg

But the real reason Jesus observed the Sabbath differently than the Jews was because He was actually doing it the way God originally intended. Whereas the Jews were not. Furthermore, if every day was a
Sabbath for Christ, then by definition, He broke the commandment by not laboring the other six days! (Exo 20:9).
5. Let's take a look at what God really said:
Gen 2:2. "He [God] rested on the seventh day from all is work." Not "is resting" from all His work.
Exodus 20:11: "The Lord....rested the seventh day." Again Gen 2:3. "In it [the seventh day] He had rested." He blessed the sabbath AFTER He had rested on it.
Heb 4:4. "God did rest the seventh day from all His works." Not "is resting"!
Did you notice they are all past and not present tense? Furthermore, If the seventh day has not ended, God should still be resting. Yet scripture indicates He is busy at work: Joh 5:17 But Jesus answered them, "
My Father has been working until now, and I have been working." See also Jer 50:25; Exo 32:16; Jos 24:31. Scripture leaves no doubt on the status of the seventh day of creation--it has long been over!!
6. The length human imagination will stretch to explain away and refrain from obeying the fourth commandment is truly amazing
