I agree with most of your post, just curious as to what you meant in the statement I quoted above. What do you mean when you say that Jes will be "brought into the kingdom"?
I'm speaking of unbelieving Jews. Until the repent and trust in Christ's atonement for their sins, they remain "outside the camp", or outside the kingdom of God. Once they are regrafted they become citizens of Christ's kingdom, which is made up of Jews and gentiles without distinction.
Speaking to the Jews, Jesus said, "Assuredly, I say to you, unless you are converted and become as little children, you will by no means enter the kingdom of heaven."
