Salvation is from God the Father, who some Jews knew, whose Son incarnate among the Jews, but was rejected by most Jews, but adopted by the Pagan, Gentile world. It’s obvious to a doorknob that many Jews did NOT know the Father revealed in the Son, for Jesus said their Father was actually the devil.
But it’s understandable that many Christians don’t know the original gospel OF Jesus because it was largely lost and replaced by a new gospel ABOUT Jesus. Today the average Christian believes that the “good news” and the gospel is that Jesus was a human sacrifice which provided the way for salvation. In the original gospel the “good news” was that all men are in fact sons of the Living God, that by faith we may realize this ennobling truth. This was unacceptable to those who suffered from the religious pride of the chosen people delusion. The Jews simply would not “share” their idea of God with others.
The cross wasn’t central to the original gospel that Jesus and the apostles taught for 3 years.
The cross is a symbol of the REJECTION by the Jews of the original gospel. That should be obvious. Jesus excoriated the Jews for their determined rejection of his gospel.
There is no greater love than one lays down his life for his friends.
