Re: If Jesus kept his mouth shut......
Would God have considered Jesus a sinner if he didn't say anything about God and the way we should live our lives?
Jesus supposedly did everything that he did of his own free will, but supposing that he chose not to say anything, what would God have done.
... etc. . .
Jesus could have gone against his father's will. That is a point often overlooked by those who believe he actually was God.
But he was born on earth for a purpose, one which he evidently volunteered for. God must have been pretty sure of him to allow this to take place. For, if Jesus had not sacrificed his earthly life, we would have no redemption.
BTW, Jesus died on the Passover as the antitypical Passover sacrifice. The anniversary of that event will take place this year on March 22.
