I’ve been thinking about this a lot, but of course, she says it better than I could:
We like things to go smoothly and as planned. Very often unexpected things intervene, and our plans go awry. We think we’ve got “problems.” There is another level at which everything that happens is being engineered. “God has no problems,” Corrie ten Boom said, “only plans.” When ours are interrupted, his are not. His plans are proceeding exactly as scheduled, moving us always (including those minutes or hours or years which seem most useless or wasted or unendurable) “toward the goal of true maturity” (Rom 12:2 JBP). Believe God. Turn the interruptions over to Him. He is at the controls.
