So even if Jesus wasn't God but just a man, and we worship him as One in the same as God, you think it's possible God may not charge us with Blasphemy? It's an interesting view but I don't see the logic.
"I further have no opinion whether Jesus was a liar or a madman. My understanding is that he was a religious Jew. "
That's very diplomatic, but if He wasn't God, he claimed to be. He claimed to be equal to God in knowledge, authority, and judgement. He claimed to be able to forgive sins and give people eternal life. The only charge laid against him at his trial that he responded to and he affirmed it, was the charge that he had claimed to be the Son of God. The rest of the charges were false and he wouldn't answer them. His followers claimed that the angels referred to him as "The Living One" and that he ascended in the Shekinah glory cloud.
"Certainly, Jews have disobeyed G-d. So has everybody. "
Agreed, everybody has. The problem I see for the Jews is that in rejecting Jesus, they have rejected God's plan of redemption.
I hope that there is some way that God can still apply the redemptive work of Jesus to the Jews, since they are asking God for forgiveness. But based on several sayings of Jesus and at least one Old Testament verse, I don't think it's likely.
There are also any number of groups that have imagined that God will give yet another chance after death. But I see no scriptural support for that. In fact based on sayings from both the OT Prophet Daniel and from Jesus, I think that is highly unlikely.
Psalms 2:12 - Kiss the Son, lest he be angry, and ye perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in him.
Daniel 12:2 - And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.
Well, at any rate, the canonized gospel accounts make this claim. Jesus himself never wrote anything down. Since I don't recognize the gospels as being inspired, I cannot vouch for the accuracy of their representation of Jesus.
The problem I see for the Jews is that in rejecting Jesus, they have rejected God's plan of redemption.
From your perspective as a Christian, sure. From the Jewish perspective, not at all.
