I was unaware of this video. The Bible states the Sabbath as being forever, even to be observed during the 1000 year reign. The Apostles still observed the Sabbath. I have yet to see anything that says the Sabbath was abolished or replaced, other than doctrine and edicts that originated with the Catholic Church.
Lucifer of course would have an interest in getting us to break as many commandments as possible. If sin is defined in the Bible as the transgression of the Law, but the Law is done away with, how do we define sin? Would not the Man of Sin try to trick us into NOT following the Law, and thus leading us to sin?
I don't proscribe to Messianic Judaism either, although admittedly, I haven't looked into this movement or doctrine.
