Where does that leave people who say Jesus was a man and a prophet like Moses and nothing more?
Non-believing Jews are just as much ignorant of God's will as we all were at some point in time. Yet, they are still fully able to receive what was promised to them from the beginning. As long as there is air to breath. It is God's will that all of them should come to Jesus, as much the same as for those in the nations. I also believe we have a huge example of how much God loves and waits for Israel to become his own again.
The God of Israel loved the world so much that he gave his only son as an offering and a banner, so that all who believe in him may be saved. How does this effect Israel? God offers all things to and through Israel, first. He gave Israel the Word, scattered her to the four winds of heaven, then sent the Spirit into the world, that as they themselves come to God they should bring back all the children of Israel with them. As an offering.
God is glorified in the restoration of Israel, as a nation and a people. It's at the heart of his Word, and the actual goal of Jesus message. The restoration of the gentiles leads to the restoration of Israel. Both united as one in the Kingdom to come.
ALL Israel is not replaced, she is not forsaken, she will be restored as new. I do not believe many in the church have properly understood the message of salvation when they preach a message of being forsaken and replaced by a spiritual people to the physical children of Israel. They act as if the Spirit is not going to do the same thing to and for the Jewish peole as he does for those in the nations.
The message to non-believing Jews shouldn't 'leave all you know and become a Christian'. If God meets you where you're at, why won't he do the same for the Jewish people? I was never moved by the turn or burn message. Well, maybe moved the opposite direction. But in the end, a negative message will always precipitate a negative response.
As I mentioned earlier, we have a huge example of love and mercy in the form of a sacrifice. His arms went out to all, met all where they were, said come to me in the most loving manner possible. Even at his own cost. His example is ours, as His Spirit is ours. I see many say they claim to walk as he did, even point out all the ways he walked, yet never seem to be able to mirror his image. Sadly, the very way they make their claims negates the image of the Holy One. One should never lord over another in anything. Especially when it comes to the children of Israel. Sadly, many who claim to be Christian mock the very people God says he loves most. And they act like Israel mocking Joseph. And we know how that story ends...
