Lot's of "Don't do that" in the NT examples I just gave..
"the saints keep the Commandments of God AND their faith in Jesus" Rev 14:12
"what matters is keeping the Commandments of God" 1 Cor 7:19
Because under the Gospel's New Covenant "The Law of God written on heart and mind" Jer 31:31-33
		
		
	 
Wrong, Bob!!
You are now off of my ignore list and I'm coming at you with both barrels blazing! 
 
We are NO longer under the Ten Commandments, Ephesians 2:15 (there is a footnote in the Scofield Bible that "man" in the KJV is the Church). READ that scripture 
carefully, Bob. The "ordinances" or Commandments have been abolished by Christ's death on the Cross. The penalties for violating them were also on the Cross. Also note in 1 Cor 7:19, the translation you quote is incorrect. In the KJV ( which the most ardent SDA of the past considered the only accurate translation) "Commandments" is not rendered with a capital "c:" just, "commandments." The commandments in view are Christ's, and "circumcision" is of the heart as Paul teaches elsewhere.
The Ten Commandments are only relevant again during the Tribulation. (As you correctly note in Rev 14). The Church is not involved because this the "time of Jacob's trouble"  (Daniel) and the Church does not go through the Tribulation (1 Thes 4 and 1 Cor 15).
The "spirit of the law" is what Jeremiah meant. Paul confirms this  in Romans 13 and in James "the royal law of liberty."
Romans 13:8-10 Christ fulfilled the Law by His death and we fulfill the law (the spirit of it)  
by loving our neighbor. 
In Romans 14:5 Paul says we can worship on
 any day we choose. The Sabbath is over!!!
As to Synergism and Monergism, SDA has always been consistently synergistic.
Don't you believe Bob, that you are saved by grace, the Law, and your own free will?
