The Ten Commandments are not an exhaustive list of sinful behavior under Mosaic Law. Is it your contention that Leviticus and Deuteronomy are not part of the Bible? Is it your contention that there were no sins outside of the Ten Commandments? That seems to be your position.
No, my position is that once God gave us the Commandments, it was what was required of us....and the New Covenant, purchased with the Blood of Jesus, makes the old obsolete...remember folks, deciding to keep up circumcision and other old ways, being chastised for having fallen from Grace by continuing to do the old covenant rituals and try to earn their own way????
If we couldn’t keep 10 simple commandments, and God decided to finally remove us from the folly of those who demanded those commandments, do you really think He will tell us that we have to parse through the Old Covenant and not do any of the things He said He didn’t like or be doomed to hell? If you do, then you also believe the Blood of Jesus isn’t enough and he wasted His time by being crucified for us.
That’s my position - I know I cannot go a whole day without a sinful thought or act and that if not for Jesus, I would be damned to Hell, but He paid the penalties for all of my sins (past-present-future) and when God was telling us about the coming New Covenant, He told us He would “Forgive their wickedness and recognize their sins no more”...
Is it your position that God lied and Jesus wasted His time - or that once He removed us from the insurmountable onus of the 10 simple commandments, He turned around and laid the onus back on us as a cruel joke to make the “uber self-righteous/holier than thou” folks believe they had the magic secret of being worthy by following the Old Covenant and ignoring the New Covenant?
