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 any 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 being made into a decent little cottage: but He is building a palace. He intends to come and live in it Himself. –C. S. Lewis, “Mere Christianity”
God rarely does anything as we would have done it or expected it.
In the 8th century B.C., God told Israel, “Your thoughts are not my thoughts, neither are your ways my ways. For as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts” (Isaiah 55:8-9).
So, when God got ready to put His earth-saving plan into effect, we may expect it to be different. Vastly different from how we would have done it.
The problem is spelled out in Psalm 50:21. God says the people lied and cheated and did a hundred bad things. Then, “These things you have done and I kept silent. And you thought I was just like you.”
We think God is like us. The ultimate folly. We expect Him to do what we would do. It just seems reasonable.
