To ask why a good God would allow suffering is to ask why a good doctor would put a needle in the backside of an infant to inoculate them. The infant doesn’t understand it, all he knows is that it is horribly painful. He can’t understand that in a way this inoculation is going to prepare him for something in the future that he is not even aware of.

And in the same way, God is a God of intention. He is a God of meaning, of purpose. He is brimming with intention and meaning. So we can rest assured that although the purposes of suffering might be hidden from us in the present life, His reasons are always wise, they are always specific, and they are always good.
