Yahweh did send His chosen people, Israel, out to battle and to defeat the nations whom He had judged should be dispossessed because of their having turned to worship of things made by men. He says why He did.
Also in the Word we are taught that the accounts of the Old Testaments are there as ensamples (examples) of what was not approved, but never has Jesus taught us to go to battle for this material world's assets.
When God orders us to go to a physical war with anhyone on His behalf, let all know, but as for me, I know we are not to war, not for this world.
Our war is not of this world but with things unseen...... It is important in the name of Love, that is god, that we do not seek excuses to war or kill in the flesh, for if the material is our goal the spiritual loses.
