Christian Science teaches us that when we think of man we are really thinking of God's expression of Himself, and we can never think of man in any other way, for he is inseparable from his divine source.
We can't feel, for example, "Well, now to work out this problem, for the next few days I'm just going to think of God and leave man right out of it" or "I'm just going to think of man and find out what man is, and what's at the root of this problem, and leave God out of it." It can't be done. The fact that Christian Science is revealing God to us as divine Principle, Mind, Spirit, Soul, Life, Truth, Love, means that Science is revealing His expression, man, to us in these terms. And the fact that we're seeing man in the radiant spirituality of his being means that what we are really seeing is God's expression of Himself.
A little boy was asked by a skeptical friend where God was. "Is He here?" asked the friend. "Oh, yes," was the instant reply. "Is He down the street?" "Oh, yes." "Is He off at the far end of town?" "Yes." "Well, if you were all by yourself on a desert island, with nobody else there, would God be there?" "Oh, yes," replied the little boy. "But how do you know?" To which came the quick response, "Because I'd be there, wouldn't I?"
