Imagine yourself as a living house. God comes in to rebuild that house. At first, perhaps, you 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 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.
C.S. Lewis, Mere Christianity
Just when all seems to be going right, challenges often come in multiple doses simultaneously. When those trials are not consequences of your disobedience, they are evidence that the Lord feels you are prepared to grow more (see proverbs 3:11-12). He therefore gives you experiences that stimulate growth, understanding, and compassion which polish you for your everlasting benefit. To get you from where you are to where He wants you to be requires a lot of stretching, and that generally entails discomfort and pain . . . Your Father in Heaven and His Beloved Son love you perfectly. They would not require you to experience a moment more of difficulty than is absolutely needed for your personal benefit or for that of those you love.Richard G. Scott, "Trust in the Lord," Ensign, November 1995
