“It is said in the scriptures that water is a form of God. But some water is fit to be used for worship, some water for washing the face, and some only for washing plates or dirty linen. This last sort cannot be used for drinking or for a holy purpose. In like manner, God undoubtedly dwells in the hearts of all – holy and unholy, righteous and unrighteous; but a man should not have dealings with the unholy, the wicked, the impure. He must not be intimate with them. With some of them he may exchange words, but with others he shouldn’t go even that far. He should keep aloof from such people.”
