We are opening up one of the most formidable of problems. Let us bear in mind, however, that we have seen one thing precluded by the mind of Christ—a belief on our part that the man who suffers or dies from an 'accident' or catastrophe of nature is thereby pointed out as punished by God. The selective, though equally natural, punishments of God are of quite another order; they single out unerringly, with the utmost subtlety and fineness, man from man. They are determined for himself by each man; he works out his own damnation as he works out his own salvation, God working with him for both. And that is why the adjustment is so accurate between the man who will not be saved and the doom that falls upon him. The calamities of earth are far too rough and ready to be God's instruments of selection. When (or if) one Grand Duke is the sole survivor of a wrecked ship and a Te Deum is sung in thankfulness to God, the mind of Christ is ignored, his plain words are ignored. 'Think ye that this Grand Duke was a man of God above all men that were on that ship?' we hear him ask. And we do not hear him say that if we all repent we shall all likewise be rescued. The kingdom of heaven is neither bought nor sold, and no repentance will purchase safety upon earth. All this lies on the face of these illuminating words spoken from the mind of Christ. But there is more to be learnt about them and from them. We are thrown back upon the mystery of the fundamental relation between matter and spirit. And if we cannot do more, we can at least consider what experience shows us every day concerning that relation and what we find when we reflect upon it. There is that tower now. Towers may be built to stand for centuries, perhaps thousands of years. There is no indication that the fall of this particular tower was due to an earthquake, against which its strength would have been useless. We may reasonably suppose that it was not strong, that there were faults in its design, or building or material, or all three or any two. A tower well designed, well built and of good materials may, perhaps, outlast mankind upon this earth. And at least it will not fall; it will only wear away and crumble. This tower fell through the fault of sinners. Was the fault moral, or was it, as we say, merely intellectual? Was there anything of the spirit about it? And we must answer that as it was fault in a human being, a spiritual and moral person, there certainly must have been moral fault. The intellectual element is not separate from the moral.
