Children at play. In case you have no experience with that, when children are free to play in house and yard all sorts of things happen. Spills, breaks, messes, fights along with all the good, fun stuff. Why do we parents not keep our children in a corner or set high on a protected shelf? It is because we know whatever they get into, however bad the mess, we are capable of fixing it or cleaning it up--no matter how ugly things were left. That clean-up doesn't happen Mary Poppins style with a snap of the fingers, either.
God brings good out of evil, beauty out of ugliness, not instantly with a snap of the fingers, but patiently, carefully over time. I have seen God work this way in my own life. Something that I thought would take an instant to bring about took four years. When it all snapped into place, I was in awe.
When you were a child and were sent off to play, how much thought did you give to instant perfection, and then keeping all around you in perfect order, clean, and sterile? I don't know about you, but my siblings and I were big fans of playing in the dirt. One day when my mother was fussing at all the fingerprints left around my grandparents house, my grandmother told her, "After the kids leave, I don't bother washing them away until about a week before the next time I know you will be visiting. I enjoy seeing their little finger and footprints scattered about the house."
