Is of the Jews yes. Jesus Christ was born a Jew. Of tribe of Judah.
"Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved."
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved. He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
