Miracles and the existence of God

Via Justin Taylor, a quotation from C.S. Lewis's Miracles:

If this week I put a thousand pounds in the drawer of my desk, add two thousand next week and another thousand the week thereafter, the laws of arithmetic allow me to predict that the next time I come to my drawer, I shall find four thousand pounds.

But suppose when I next open the drawer, I find only one thousand pounds, what shall I conclude? That the laws of arithmetic have been broken?

Certainly not! I might more reasonably conclude that some thief has broken the laws of the State and stolen three thousand pounds out of my drawer.

Furthermore, it would be ludicrous to claim that the laws of arithmetic made it impossible to believe in the existence of such a thief or the possibility of his intervention.

On the contrary, it is the normal workings of those laws that have exposed the existence and activity of the thief.
