God's command for Israel to execute total war on the Canaanites has a rational—and yes, Christian—explanation. He is not cruel; there is a benevolent reason.

We need to guard our minds to that demonic spirits do not wrest our spiritual sword away from us, quoting scriptures to support doctrines of demons.

God has never given mankind the prerogative to determine whether war is just or not. God has promised to protect us, conditioned on our obedience to our covenant.
