The worship of CHWH (God-Almighty) on the wrong day and in the wrong places is the first and worst sin that will lead many men into hell, not the below listed ones.

It is called: THE DESECRATION OF THE REST AND SIGN OF CHWH JHWH YHWH OKIKE ABIAMA (GOD ALMIGHTY OF Abram) TO MAN. Actually it is the reason for THE GREATEST DILEMMA verse in the scripture:

Matthew 7:21 KJV

Not every(Not even) one (churchian) that(who) saith(calls) unto me, Lord(Jesus), Lord(Jesus):

shall enter into the kingdom of the king of heaven;

but he that doeth the will of our Father which is in heaven.

(the will of our father or heaven/Orion is the decalogue and its heart is the 4th LAW! This is a secret)

Matthew 7:22 KJV

(On judgment day) Many(of them) will say to me in that day, Lord (Jesus), Lord (jesus), have we not prophesied in thy name (Lord Jesus)? and in that name (Lord Jesus) have cast out devils?

and in that name (Lord Jesus) have done so many wonderful works?

Matthew 7:23 KJV

But then will I (look them in the eyes and) and profess unto them, (saying.. my name was never Jesus!!!!)

(In fact) I never knew you: depart from me, ye that work iniquity (the lawless who says the law of CHWH is done away with,

and profane the Shihabata(Sabbath) when you worship on the first day of the sun's creation instead of the last day of the week which is my Holy Rest). Beware the 7th day of the Roman week isn't actually the ancient Shihabata day. With wisdom every Hebrew can figure it out on their own or you must embark on a pilgrimage to NegroLand so you can have knowledge of that classified secret!
