I have been a preacher 40 plus years, I understand the bible. Can you not read? Because I explained why it is as it is in vivid detail. Yes, God's bride rejected Jesus as their Messiah, so God forsook them for nigh 2000 years but God had a plan. Question, do you really think if Jews had tried to take the Gospel unto the whole world the whole world would have accepted Jesus? God used Israel to birth the Messiah, the promise to Abraham, then God used 12 men and their underlings to teach the Gentiles how to Evangelize the whole world. If God had not allowed the Diaspora, the Gospel would have been perverted into some type of legalistic Judaism , so God knew exactly what needed to be done, Gid used His bride to birth the Messiah, then he used the Church or Jesus' future Bride to evangelize the whole world, then God will use His bride Israel to set up His sons 1000 year reign on earth.
The whole Bride thing is just to show us how our relationship with God is supposed to be pure like a relationship with ones spouse. Israel were put forth as an example. Have you ever seen Christian friend that FALL then get back right with God? So, Israel only rejected Jesus the Promise because they got sidelined with THE LAW, the never understood fully that it was The Promise which came over 400 years before the Law of Moses came. So, the fell because of Paul said.......LACK of FAITH....... and when that faith returns so will Israel unto God.
