The great majority of historians, clergy, and religious commentators believe that Jesus (Joshua) was an apocalypticist -- a fancy word for those who believe (in any era) that the end is near, a great event--probably very destructive-- and a new age will begin. For Christians, and some Jews, this means that the judgment day will occur, and the good will be separated from the evil. The good will live happily in God's kingdom and the evil will suffer the torments of hell. It is undoubtedly true that many Jews of the so-called Second Temple Era believed that the apocalypse was imminent, and may holy men as well as not-so-holy men were preaching this very thing.
I don't believe that Jesus was among them. He was assuredly a devout and committed believer in an all-powerful and all-wise God, and he was convinced that it was his duty--and privilege--to do God's will. He was all too aware of the sufferings of his people under Roman rule, authoritarian, vicious and deeply cruel. And the cruelest man of the era was Pontius PIlate. It was also clear to Jesus that Pilate was intent on provoking a rebellion, which he would then joyfully crush with the full weight of the empire. At the Passover of Jesus's death, probably 33 C.E., Pilate had requested from the Syrian Legate additional troops. He had already quietly brought all the soldiers under his command from Caesarea to Jerusalem, dispersing them from Herod's Palace to the Antonia Fortress, where he waited anxiously for the proper moment.
Jesus understood this very well--the apocalyptic event that awaited his people was not the arrival of God's kingdom, but the holocaust planned by Pilate. It was from this understanding that Jesus acted as he did, and it was to save his people that he sacrificed himself. He did not die for some nebulous concept of "our sins," but to thwart the villainous Pilate. He succeeded, but only for a while. In 66, goaded beyond belief, the Jews erupted in rebellion, and there was no Jesus of Nazareth to save them.
