I can't remember if this is in an earlier blog but it it still worth putting down again.
So here it is:
" Do not forget this. At first it is natural for a baby to take its mother's milk without knowing its mother. It is equally natural for us to see the man who helps us without seeing Christ behind him. But we must not remain babies. We must go on to recognize the real Giver. It is madness not to. Because, if we do not, we shall be relying on human beings. And that is going to let us down. The best of them will make mistakes; all of them will die. We must be thankful to all the people who have helped us, we must honor and love them. But never, never pin your whole faith on any human being; not if he is the best and wisest in the world. There are lots of nice things you can do with sand; but do not try building a house on it. "
( CS Lewis p494 A Collection of works)
PS You can't build on sand unless you are on a Casas Por Cristo trip in Juarez, Mexico.
