From the The Jewish Virtual Library:
"The Jewish belief that the Messiah's reign lies in the future has long distinguished Jews from their Christian neighbors who believe, of course, that the Messiah came two thousand years ago in the person of Jesus. The most basic reason for the Jewish denial of the messianic claims made on Jesus' behalf is that he did not usher in world peace, as Isaiah had prophesied: "And nation shall not lift up sword against nation, neither shall they learn war anymore" (Isaiah 2:4). In addition, Jesus did not help bring about Jewish political sovereignty for the Jews or protection from their enemies."
We believe that the earthly kingdom will be established when Jesus comes for the second time. Our Messiah has already come, and He is coming again. The confusion lies around the purposes for His first and second coming.
But please do not compare us to the Islamics. We are commanded to pray for the peace of Jerusalem, and the Jewish people are our brothers and sisters. We love the Jewish people and pray for their salvation, the Islamics hate them and try to bring abour their anhilation
In no way would a true Christian ever move to harm Isreal. We believe at the establishment of Christ's thousand year reign on earth, that all nations will be judged by the way they treated Israel.
