Christians accept the New Testament as our complete guide to salvation. Not completely rejecting the Old Testament, but knowing it's not our guide on how to live today. And nowhere in the New Testament are we commanded to make war on all those who reject Christ. And for the millionth time, if people want to refuse to believe in Christ, want to live under Islam, that's their business. But to not acknowledge that there's a significant percentage of Muslims actively looking to spread Islam by any means necessary, including violence, is putting your head in the sand.
