Actually that's not true. The development of the doctrine of two messiahs was of a post-Christian date. Before that time, and at the time of Jesus, the Messiah was not the focus of Rabbinic theology. He was, to put it bluntly, a means to an end. It was the restoration of the Davidic kingdom that the Jews lived in hopes of, the messiah was just the person who was going to bring it to pass. Much of what later became associated with messiah was previously viewed as the ministry of the forerunner, including things like raising the dead.
But as for Jesus' words, yes, he came to lay down his life a ransom. And he accomplished that. But then he took his life back up again and conquered hell, death, and the grave. You have to realize there is a "the rest of the story" to this, and you're leaving out a big part.
The problem the Jews had, and I believe the dispensationalists have the same blindness, is that you don't understand what "kingdom" Jesus came to lay down his life to establish. It isn't an earthly kingdom of dust and stone. The kingdom which Jesus' death opened the way into is the kingdom of Heaven, God's kingdom, an eternal kingdom where there is no sin or sickness or suffering or weeping or death. That's where the Jews missed it. Their eyes were and still are so fixed on and blinded by the glory of an earthly kingdom that they cannot or will not lift their eyes to heaven to see that kingdom that Abraham longed for and now dwells in. Remember Jesus told the Jews not to lay up treasures on earth, but to lay up treasures in heaven. That's why the Jewish religious authorities hated Jesus, because he didn't deliver them from Rome and set them up as rulers over all the earth as they were expecting the Messiah to do.
I am very well acquainted with Hebrews and I must say I disagree with your view of the efficacy of the Mosaic sacrifices. They most certainly did cleanse men of their sin, but to quote Paul, "for the blood of bulls and goats sanctifieth to the purifying of the flesh." In other words, the cleansing afforded by the Mosaic sacrifices was only skin deep, but it was enough that they made the flesh clean because it was of the flesh of Israel that Jesus was born, his spirit was all of God.
Of course, it was a period of grace God allowed to the Jewish people. They first had to be given the opportunity to hear the Gospel and be saved from the judgement that was coming. That's why Jesus told his disciples to go first to Jerusalem and then Judea, and then Samaria and then to the outermost parts of the earth. The Gospel was to the Jew first, and only after all of Israel had heard the Gospel did the end come and the nation was judged and destroyed.
But that's just the point. Either you believe it is God's "plan" to have a rebuilt temple and reinstitution of the Mosaic sacrifices or not. I do not believe that is God's plan at all. Those things were types and figures which foreshadowed Jesus' sacrificial death and now that the true has come and the shadows have passed away I don't believe for a moment that God will allow what would be a repudiation of His Son's atoning death.
But that's just it, that's the whole point of human history. It has been engineered by God for the purpose of glorifying Jesus. Without that pivotal event in history, to which the Old looked forward, and to which the New looks back, there wouldn't be any point to human history, it would just be what the evolutionists say, blind accidents of nature without meaning or purpose.
The Scriptures says everything in the whole creation was not only made by Jesus, and through Jesus, but that it was made "for" Jesus. He is the reason the world was created, why man fell, why the angels rebelled, and why every moment of history has happened just the way it has happened ... "for Jesus."
The Cross stands at the center of time and history. Everything before it looked forward to it. And everything since flows from it. It divided time in half, B.C. + A.D. Jesus isn't just the reason for the season, Jesus is the reason for everything.
In Christ,
