The new Covenant has nothing to do either with ethnic Israel, nor with mankind in general, but is only for the Spiritual Israelite individuals; the true Overcomers, who are born again faithful Christian believers; the ones who bear the proper fruit. Matthew 21:43, Galatians 5:22-23
The Bible’s restoration prophesies do not relate to those who call themselves Jews, or to the citizens of the State of Israel, for they are a part of the world that Jesus spoke about in Revelation 2:20-23, John 15:6, Matthew 21:33-46
Bible teaching could not be clearer: it is we Christians who are the inheritors of God’s Promises to the Patriarchs, Galatians 3:26-29, and it cannot be that God will give His holy Land to anyone who rejects His Son and fails to obey the Commandments.
