Jews at that time did not believe in salvation of non jews... and that's why Paul sets the record straight.Ezekiel 36-37 harmonises with the New Testament, not contradicts it. The promises to Israel now belong to all those of faith regardless of race because they are all Israel. Paul wrote, "For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God” (Romans 2:17, 25, 26, 28, 29).
God looks at the heart of man and not his blood.
If you read Ezekiel 36-37... you see that God has a bone to pick with the nations and especially Edom who took His land as if it was their own and plundered and left it desolate. You see God lifting His hand and solemnly swear that His land will again produce branches and bear fruit for His people who will come home.
Furthermore God says it is for the sake of His name which was profaned by His people wherever they went... that He will bring them back and so also show the nations roundabout that He is God.
It is a historical fact that the jews are back... but it was also a biblical promise.
Paul said in Romans 11 that God blinded the jews... but of course if you say God did not... we must admit Paul was wrong. L0LGod never blinded the Jews, they blinded themselves with their sin and rejection of Him. God gave the Jews so many chances to come back to Him. Their rejection of Him could not continue forever. Eventually they lost their state as the chosen nation. Jesus Himself told them that, "The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof" (Matthew 21:43). Jerusalem had not brought forth fruit for a long time because of their rejection of God, so the gospel was taken from and given to the Gentiles. In the New Testament the gospel goes out mainly to the Gentiles and to this day the true gospel of Christ is with the Gentiles mainly who joined the olive tree and are now part of Israel. Spiritual Israel is sadly mainly made up of Gentiles not Jews.
You talk an awful lot... but do you listen to the shepherde ?
