Imagine yourself as a living house. God comes in to rebuild that house.
At first, perhaps, you can understand what He is doing. He is getting
the drains right and stopping the leaks in the roof and so on: you knew
that those jobs needed doing and so you are not surprised.

But presently He starts knocking the house about in a way that hurts
abominably and does not seem to make sense. What on earth is He up to?
The explanation is that He is building quite a different house from the
one you thought of — throwing out a new wing here, putting on an extra
floor there, running up towers, making courtyards.

You thought you were going to be made into a decent little cottage: but He is building a
palace. He intends to come and live in it Himself.
