Inevitable. Why is religion always about killing?
This enrages me:
(...) What is the testimony of Scripture as to the primary cause of war? It’s our wicked hearts.
Religion and ideology are simply the means through which we exercise the wickedness in our hearts. To think, as many outspoken atheists do, that if we can somehow remove our “silly need for religion,” we can somehow create a more peaceful society, is to have a mistaken view of human nature. The testimony of human history is that if we remove religion, something else will take its place, and that something is never positive.
