Evidence of God's children---wmscog

God commanded to keep the seventh day as the holy feast of God.
“Speak to the Israelites and say to them: ‘These are my appointed feasts, the appointed feasts of the LORD, which you are to proclaim as sacred assemblies. ” ‘There are six days when you may work, but the seventh day is a Sabbath of rest, a day of sacred assembly. You are not to do any work; wherever you live, it is a Sabbath to the LORD… (Leviticus 23:2-3)
The Sabbath day is a sign between God and the children of God.
“Say to the Israelites, ‘You must observe my Sabbaths. This will be a sign between me and you [God and God's people] for the generations to come, so you may know that I am the LORD, who makes you holy. ” ‘Observe the Sabbath, because it is holy to you. Anyone who desecrates it must be put to death; whoever does any work on that day must be cut off from his people… (Exodus 31:13-14)
I [God] gave them my decrees and made known to them my laws, for the man who obeys them will live by them. Also I gave them my Sabbaths as a sign between us, so they would know that I the LORD made them holy. (Ezekiel 20:11-12)
Those who do not keep the Sabbath day profane God, which is the evidence of false prophets.
Her priests do violence to my law and profane my holy things; they do not distinguish between the holy and the common; they teach that there is no difference between the unclean and the clean; and they shut their eyes to the keeping of my Sabbaths [they ignore the Sabbath: GNT], so that I am profaned among them. (Ezekiel 22:26)
