Your question is not something that is Biblical, you isolate the Sabbath when God did not. I do not think we can disobey God on anything and live, without repenting and turning from. Pro28:13 Sin is what separated us in the first place Isa 59:2 its not how we are reconciled. Rev14:12You ignored my questions and insist on continuing to conflate the old and new covenants. I can see that your indoctrination runs very deep.
Its what the apostles taught too
Heb 5:8 though He was a Son, yet He learned obedience by the things which He suffered. 9 And having been perfected, He became the author of eternal salvation to all who obey Him,
God said If you love Me, keep My commandments Exo20:6 John14:15 I do not believe anyone who does not love God and submits to Him will see heaven. Heb10:26-30 Mat7:21-23 Luke6:46-48 and to be honest I am not sure why anyone would not want to do what He asks. If we trust what He wrote in 9 of His Ten Commandments Deut4:13 Exo34:28, why not trust and have faith in Him fully? We have to have room for faith so to forget the only commandment God said to Remember and made holy and blessed by the Creator of the Universe is just not logical to me, but guess it will sort itself out soon enough.
