They come natural to us; they are involuntary, like breathing.
There is no personal merit in breathing.

But the reverence which is difficult, and which has personal merit in it, is the respect which you pay, without compulsion, to the political or religious attitude of a man whose beliefs are not yours.

You can't revere his gods or his politics, and no one expects you to do that, but you could respect his belief in them if you tried hard enough; and you could respect him, too, if you tried hard enough.

But it is very, very difficult; it is next to impossible, and so we hardly ever try.

If the man doesn't believe as we do, we say he is a crank, and that settles it.
