It’s very, very nice to have a society more or less enlightened by biblical ideals, but absolutely essential for Christians to actually evangelize, i.e. play some part in winning souls.
I figure that defending invasion of a Judeo-Christian society responsible for the most prosperous, charitable, generous, productive nation in history, especially making that defense as civilly and peacefully as possible — i.e., burning paper instead of people — would play some part in winning souls, especially when those souls were converted Muslims who could be confident that their new religion would not expect them to be slaughtered in the name of “peace.”
