Get out of the Old Testament. Israel is no longer God's people. He cut them off when they rejected Christ. Christians were grafted on to the tree when the branch of Israel rejected Him. When Israel finally figures out the truth, they will be grafted back onto the tree.
Jesus came to preach the gospel to the Jews first. After he died, then the disciples were told to go preach it to the gentiles and convert them to Christ. The Jews that accepted Christ, became "Christians"... i.e. followers of Christ or disciples of christ. (Messanic Jews). The gentiles that accepted Christ also became "Christians".
Israel is not a Christian state. It is a Jewish state. The government is secular and can defend itself quite well, since the U.S. government supplied them with all their nuclear warheads.
What exactly am I suppose to support? The U.S. government takes american taxpayer money to support illegal weapon sales to another country, to start wars.
God said, "Thou shalt not kill."
He did not say, "Thou shalt not kill, except in time of war."
Get right after it sinner. Support Israel. Support the US. Support all their illegal wars, invasions and occupations of other soveriegn nations.
We'll see how God deals with you, Israel, the US and other war mongerers.
