John 3:16 only has a very finite few words. Do you claim this is "only for the Jews" or "only for the Gentiles?" Because it's awfully hard to hold you still when your response is to always claim the passage is inapplicable.
Joh 12:32-33 KJV
(32) And I, if I be lifted up from the earth, will draw all men unto me.
(33) This he said, signifying what death he should die.
Nothing about his death in the gospel to the Jews? Want to double down your audacious challenge to the resurrection?
Joh 2:18-22 KJV
(18) Then answered the Jews and said unto him, What sign shewest thou unto us, seeing that thou doest these things?
(19) Jesus answered and said unto them, Destroy this temple, and in three days I will raise it up.
(20) Then said the Jews, Forty and six years was this temple in building, and wilt thou rear it up in three days?
(21) But he spake of the temple of his body.
(22) When therefore he was risen from the dead, his disciples remembered that he had said this unto them; and they believed the scripture, and the word which Jesus had said.
Seems your bet would lose there as well.
Luk 24:44-47 KJV
(44) And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me.
(45) Then opened he their understanding, that they might understand the scriptures,
(46) And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day:
(47) And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.
How do you miss that part, of "Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day?"
And how do you miss that part, that "repentance and remission of sins should be preached ... among all nations, beginning at Jerusalem?" Jerusalem is the beginning of all nations, Judah is not a special case. Gentiles are also preached that same gospel of repentance and remission of sins.
