That's strange. Jesus Christ lives today, and you can easily talk to people who have been transformed by our Lord's vibrant, exuberant, and redemptive personality. All of "life, the universe, and everything" can be understood and appreciated when viewed through the lens of this one man's biography. The redeemed of the Lord experience great gladness in knowing that their sins are atoned for, that new birth / new life is possible, that God is present among us today, that the Eternal has intruded into time through Jesus of Nazareth, and continues to do so into our lives through that same Person. Our God is good, He has made Himself known, and life is deeply significant because of Jesus.
Jewish folks do a lot of overcompensating, since the most important event in all of recorded history happened in their back yard, on their watch -- and most of them missed it. Were asleep at the switch. To their eternal loss.
But they don't need to remain outside the party, in the cold with their noses pressed against the plate glass window. They got the first invitation, the first Christians were Jewish, and the invitation is still good. The founding pastor of my church is a Jewish man who got the point, and got with the program.
Come on in, the water's fine! We all (well, almost all of us) wish you well, for this life and for eternity.
Frankly, that is a meaningless observation. There are millions of Mormons who have had a burning in the bosom and have been transformed, stopped doing drugs and alcohol etc. Does that make Mormonism valid? No. Same can be said of Islam. Mormonism, Islam and Christianity are ALL heretical offshoots of Judaism.
G-d is not done with the Jewish people. If you read the prohets, Joel, Zachariah, Ezekiel and Isaiah, the one consistent theme is this. G-d has exiled the Jewish people due to their sin. The Nations have afflicted the Jewish people but have gone way too far. G-d will bring back the Jewish people from the Nations. The Jewish people will be forgiven by G-d, cleansed and the world will be astonshed. The gentile nations will be judged for their abuses. The gentile nations will come to Israel to learn of G-d and the Law and reject the lies they have been taught all along.
That is a synopsis what the Tanakh (OT) teaches.
