MacDonald on the places where God works

This quote has often sustained my wife and me through the years since 1996 when we first came acroos it. From George McDonald in, I think, The Curate's Awakening.

"Because you don't see what can be done, you say God can do nothing--which is like saying there cannot be more within His scope than there is within yours. One thing is clear: if He saw no more than lies within your sight, He could not be God. The very impossibility you see in things points to the region God works in."
