G'day Didymus,
To say that fighting against Israel is to be fighting against God is a gross misrepresentation of Scripture IMO. Under the Old Covenant this was true, however in Christ i.e., in the New Covenant the only people particular to God are those who are "born from above" -there is no ethicity involved any longer.
Rom 2:28-29 (NKJV) 28For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh; 29but he is a Jew who is one inwardly; and circumcision is that of the heart, in the Spirit, not in the letter; whose praise is not from men but from God.
John 8:39 (NKJV) 39They answered and said to Him, "Abraham is our father." Jesus said to them, "If you were Abraham's children, you would do the works of Abraham.
This was once said about Israel:
Ex 19:3-6 (NKJV) 3And Moses went up to God, and the LORD called to him from the mountain, saying, "Thus you shall say to the house of Jacob, and tell the children of Israel: 4"You have seen what I did to the Egyptians, and how I bore you on eagles' wings and brought you to Myself. 5Now therefore, if you will indeed obey My voice and keep My covenant, then you shall be a special treasure to Me above all people; for all the earth is Mine. 6And you shall be to Me a kingdom of priests and a holy nation.' These are the words which you shall speak to the children of Israel."
This is now true of the people of God -believers:
1 Peter 2:8-10 (NKJV) 8and "A stone of stumbling and a rock of offense." They stumble, being disobedient to the word, to which they also were appointed. 9But you are a chosen generation, a royal priesthood, a holy nation, His own special people, that you may proclaim the praises of Him who called you out of darkness into His marvelous light; 10who once were not a people but are now the people of God, who had not obtained mercy but now have obtained mercy.
See the difference Christ makes -since the New Covenant ALL believers are His special possession and land no longer is an issue.
