Even only in the matter of the Sabbath, your statement is absurd. Y'all don't keep the ten, not to mention the rest.
i feel sorry for those who believe the old covenant and it’s laws are still valid today. it is an insult to the blood of Christ, which seals the new covenant.
the lost will continue to try and keep the law ( including the Sabbath ) the body of Christ will follow the law of Christ.
