Every SDA needs to read 2 Corinthians chapter three,
where Paul says the apostles are the ministers of the new covenant and the law of the Spirit that gives life, which he contrasts with the ten commands, given to Moses on the mountain,
that brings death..
The Ten Commands are called the ministration of DEATH, the letter which KILLS, and the ministration of CONDEMNATION.
2Co 3:6 Who also hath made us able ministers of the NEW testament; not of the letter, but of the SPIRIT :
for the letter KILLETH , but the spirit giveth life.
2Co 3:7 But if the ministration OF DEATH written and engraved in stones (The Ten Commandments) was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be DONE AWAY:
2Co 3:8 How shall not the ministration of the spirit be rather glorious?
2Co 3:9 For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory.
2Co 3:10 For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth.
2Co 3:11 For if that which is DONE AWAY was glorious, much more that which remaineth is glorious.
The reason the Ten commands kills, brings death, and condemnation, and has been done away, is due to the fact that the penalty under the law for breaking many of the Ten, was being put to death by stoning.
The penalty for homicide - being put to death by stoning:
Exo 21:12 He that smiteth a man, so that he die, shall be surely put to death.
The penalty for not honoring your mother and father: put to death by stoning:
Lev 20:9 For every one that curseth his father or his mother shall be surely put todeath: he hath cursed his father or his mother; his blood shall be upon him.
The penalty for adultery: put to death by stoning:
Lev 20:10 And the man that committeth adultery with another man's wife, even he that committeth adultery with his neighbour's wife, the adulterer and the adulteress shall surely be put to death.
The penalty for breaking the sabbath by doing any work, such as picking up sticks for kindling: put to death by stoning:
Exo 31:14 Ye shall keep the sabbath therefore; for it is Holy unto you: every one that defileth it shall surely be put to death: for whosoever doeth anywork therein, that soul shall be cut off from among his people.
If the Ten Commands are still in effect, then the penalty for breaking them is still in effect - thus those who insist on keeping the covenant that contained the Ten Commands, are breaking the law themselves, by not stoning to death those who break them.
You can't have one without the other.
Imagine you were doing a ride along with a police officer, and you see that he ignores traffic law violations: speeding, running red lights, reckless driving, drunk driving, etc.
During the conversation you have with the officer, he says, "yes, I believe in the traffic laws. I keep those laws, myself - I just don't enforce them".
How do you know the traffic laws are still in effect? They enforce them. Break them, and the penalty under the law is given to the law breaker.
Sabbath day keepers, and Ten Commandment keepers are saying, those commands are still in effect and we keep them, but we just don't enforce them, as is required BY the law.
