He is the son of God. He was born of the Virgin Mary. And that he is the Messiah that is foretold in the Old Testament, that Jewish people believe the Old Testament tells of the forecoming of a Messiah. And people that are Christian believe that Jesus Christ is the Messiah. And people that are Jewish believe that Jesus Christ was not the Messiah. He was also said to be sent to cleanse the sin of man, that man is born with sin. And that because Jesus died on the cross and suffered in hell for three days before he was resurrected, that he did that to cleanse man of sin.
