If a statue of God were standing right there, you wouldn't dare do the things you're doing now. But when God himself is actually present inside you, seeing everything and hearing everything, you're not ashamed of your thoughts and actions. You don't understand your own nature. You're just asking for God's anger.
So why do we worry when we send a young man out from school into real life? We worry he'll act badly, eat badly, sleep around improperly. We worry that his shabby clothes will make him feel worthless, or that nice clothes will make him arrogant. But this young man doesn't know his own God. He doesn't know who's with him as he goes out into the world.
Can we stand it when he says, "I wish I had you with me, God"? Don't you already have God with you? Are you looking for some other god when you already have him? What else could God possibly tell you?
And if an image of God were present, you would not dare to do any of the things which you are doing; but when God himself is present within and sees all and hears all, you are not ashamed of thinking such things and doing such things, ignorant as you are of your own nature and subject to the anger of God. Then why do we fear when we are sending a young man from the school into active life, lest he should do anything improperly, eat improperly, have improper intercourse with women; and lest the rags in which he is wrapped should debase him, lest fine garments should make him proud. This youth (if he acts thus) does not know his own God; he knows not with whom he sets out (into the world). But can we endure when he says, "I wish I had you (God) with me." Have you not God with you? and do you seek for any other when you have him? or will God tell you anything else than this?
