Struggling w/ Jesus and Jewish law

Struggling with this question regarding Jesus as a messiah given Jewish prophecy. With regards to formatting of this post, I recently had a stroke and so have to use speech to text; I mean no disrespect. I should also add that I'm asking a sincere question not trying to be inflammatory and definitely not trying to be disrespectful of anyone's beliefs. I struggle with accepting Jesus as the messiah given Jewish prophecy/law. So for example: Isaiah 53 speaks of the Messiah coming as a suffering servant, One who is led as a lamb to the slaughter and who takes our sorrows, infirmities, and punishment on Himself. In this particular case for example no one can fulfill my obligations under Jewish law; facetious as it may sound no one can honor the commandments on my behalf or eat kosher on my behalf these are my obligations so I do not understand the Christian belief that through Jesus I am saved. He cannot my sins and my responsibilities for atonement onto himself per Jewish law. Second, the Talmud as well as historical documents recognize two messiahs: one messiah being the son of Joseph and two Davidic messiahs. From my reading of the historic documents Jesus clearly meets the criteria of the messiah son of Joseph while does not necessarily meet by Jewish standards the criteria of the Davidic messiah. Why can we not accept Jesus as the messiah ben joseph? Third, I don't understand how the current Christian practice doesn't violate the Jewish prohibition against idolatry or the 1st commandment. Fourth, is it not sufficient for me to consider Jesus a rabbi? Thank you in advance for your help and insight.
