My heart is so tired - Rudyard Kipling

Many religious people are deeply suspicious. They seem—for purely religious purposes, of course—to know more about iniquity than the unregenerate.

... it's always best to tell the truth.

Go back to Earth with a lip unsealed—go back with an open eye,
And carry my word to the Sons of Men or ever ye come to die:
That the sin they do by two and two they must pay for one by one—
And the God that you took from a printed book be with you, Tomlinson!
