This is true
Exodus 20:6, "Remember the Sabbath Day, to keep it holy."
Mattithyah 5:18, "For truly I say to you; Unless heaven and earth passes away, one yodh--the smallest of the letters--will in no way pass from the Law, until all things are perfected."
Luke 16:17, "But it is easier for heaven and earth to pass, than one yodh of the Law to fail."
However the the world has, as a whole been tricked by the lies of satan
Revelation 12:9, "And the great dragon was cast out, that old serpent, called the Devil, and Satan, who deceives the whole world..."
I would think it very possible that out of those who say they follow the Messiah less than 1 in 5 actually follow Him in truth.
Can any of the people who dont believe in 7th day Sabbath tell me what this verse means?
