Now we’re back to Scripture proving Scripture. That’s how. If one’s interpretation contradicts Scripture as stated over and over again (not removed from its context) contradicts Scripture...guess who’s wrong. (Clue: Since Scripture IS the only authority, that would be the one who is wrongly interpreting it, not Scripture itself.)
As for “protection” from sin, who said He was some kind of life vest? He guides, but no I don’t think I ever stated one was COMPELLED, but it’s a strange sort of Christian who would not want to.... Again, since we are ALL sinful creatures, we will never be sinless on this Earth. None of us (and yes, that includes Mary). Only one was and is sinless in human form and that’s Christ.
Have you ever had a doctrinal discussion with a Jehovah's Witness? They do exactly that, and with the same alacrity of most Protestants I might add.
It doesn't make them right.
