This is for a friend. He asked for another friend: where is it that Jesus says he is Messiah?
John 4:25-26, where the woman at the well told him, I know Messiah is coming, and Jesus replies, "I who speak to you am." That's the way the Greek says it. He plainly tells her he is the Messiah and God all at the same time.
John 10:22-42, where the Jews ask him to tell them plainly if he is the Christ. He said "I did tell you but you do not believe because you are not my sheep." He also tells them that he and the Father are one, causing them to pick up stones because he's claiming to be God.
Reminder that Christ and Messiah are the same word in two different languages.
He also called himself the Son of Man, which was synonymous to Jews as a title for the coming Messiah.
1 John 4:1-3, "Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world. 2 This is how you can recognize the Spirit of God: Every spirit that acknowledges that Jesus Christ has come in the flesh is from God, 3 but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world."
Okay, so that does not specifically say Jesus is the Messiah, but it does condemn anyone who preaches a different Jesus than the one revealed in the Scriptures, aka, the Messiah.
John is very obvious about Jesus being Messiah and God in the flesh. Paul always refers to him as Christ Jesus. Jesus himself said in John 14:6, "I am the way, the truth, and the life. No one comes to the Father except through me."
Don't listen to the Jesus Seminar. He really did say the things he says in John.
All this is in response to another video by a famous preacher who says that the Jews didn't sin in killing Jesus because Jesus never claimed to be the Messiah. If this preacher dies still believing that he will be condemned forever.
I'm all for supporting Israel, but we must remember that all true Christians are the completed Jews. The biological Israel rejected Christ and forfeited their salvation. Only those who accept Christ's sacrifice in their place and accept his righteousness imputed to them are Israel and will live with God in eternity. This is only possible if Jesus is the Messiah.
