Scripture is convoluted and weak!
Some cite Hebrews 4: 4-7 as indicating that the church should no longer keep the seventh day Sabbath because Y'shua is our Sabbath rest. That is not what Hebrews 4 is talking about. In chapter 3 of Hebrews, “God’s rest” does not refer to the seventh day Sabbath, but to the blessing Yahveh had prepared for His people when they entered the Promised Land.
Hebrews Chapter 4, generally refers to the rest Yahweh has prepared for us in Y'shua’s kingdom. Although the seventh day Sabbath is specifically mentioned in Hebrews 4:4-7; in context, that passage seems to be referring to the fact that those who Hear Y'shua’s voice and obey his commandments will enter into the rest God has prepared for them and that those who hear His voice and do not obey Him, will not enter into that rest.
It would seem that the seventh day Sabbath is used here only to indicate the type of rest being described.
The Hebrews this letter was written to could not identify with the rest Yahveh had planned for them in the Promised Land because they never experienced it as He intended them to. They could, however identify with the Sabbath rest, which is a shadow of the rest this passage refers to. In any case, nothing in this passage indicates that the Fourth Commandment has been rescinded or that the gentile church has been exempted from obeying it.
