The world is God’s classroom, and we are all students in it.
Much of the curricula is assigned by default – the circumstances we are born into, the mistakes of our own making, the troubles and afflictions inherent in a fallen world, the love or cruelty of our fellow classmates, etc.
Don’t let faulty thinking lead you to believe God has assigned all the lessons; most of them are a consequence of The Fall or the results of our own decision making. If you want to blame someone, try Adam and Eve or yourself. However, sometimes out of love and a desire for what is best for us, God will engineer circumstances and situations to show us a lesson we need to learn. It may be a wearisome chap from whom we learn patience, for example.
As students, we are a divergent lot, a few eager to learn, some reluctant, and too many refusing to learn anything at all. I will leave you with a thought that came to me as I was writing this post. The class is not over until the lesson is learned.
