Mankind is notoriously too dense to read the signs that God sends from time to time. We require drums to be beaten into our ears, before we should wake from our trance and hear the warning and see that to lose oneself in all, is the only way to find oneself.
The world is touched by sacrifice. It does not then discriminate about the merits of a cause. No so God - He is all seeing. He insists on the purity of the cause and on adequate sacrifice thereof.
The first and last lesson of religion is, "The things that are seen, are temporal; the things that are unseen, are eternal." It puts an affront upon nature.
I have come to the conclusion that whether or not a person is a religious believer does not matter. Far more important is that they be a good human being.
