Denying God existence is denying Israel right to exist. In 1948, a long waited prophetic event came to past. The Jews were given the right to exist in there own land, again.
Then he said to me: "Son of man, these bones are the whole house of Israel. They say, 'Our bones are dried up and our hope is gone; we are cut off.' Therefore prophesy and say to them: 'This is what the Sovereign LORD says: O my people, I am going to open your graves and bring you up from them; I will bring you back to the land of Israel. Then you, my people, will know that I am the LORD, when I open your graves and bring you up from them. I will put my Spirit in you and you will live, and I will settle you in your own land. Then you will know that I the LORD have spoken, and I have done it, declares the LORD.' Ezekiel 37
I believe that God has a plan for this nation, which He intends to be a blessing to all the nations of the earth. "I will bless those who bless you and curse him who curse you" Gen 12:3.
The truth is the body of Christ (The Church) and Israel (nation) have their purpose in the fulfilment of Bible prophecies. The Church commission is to spread the gospel of salvation to Jews and gentiles (gospel for the forgiveness of our sins and a promise of everlasting life) and to preach the Kingdom of God (Christ return) to all nations as a witness. It is not commission to force conversion to the entire world. The restoration of the nation Israel is to prove to the world nations that God love Israel, and to inform the entire world that the end time of this world government system is at hand and that all nations will give account on their behaviours toward all Jews worldwide and the nation Israel.
