God did not put this wondrous world about your young souls to tempt or to mislead them.

If you ask Him for a fish, he will not give you a serpent.

If you ask Him for bread, He will not give you a stone.
So use your eyes and your intellect, your senses and your brains, and learn what God is trying to teach you continually by them.

I do not mean that you must stop there, and learn nothing more.

Anything but that.
There are things which neither your senses nor your brains can tell you; and they are not only more glorious, but actually more true and more real than any things which you can see or touch.
