Why does god let bad things happen?

Some of you, perhaps, have seen a man who can read the past life of others and foretell the future. How is it possible for any one to see what the future will be, unless there is a regulated future? Effects of the past will recur in the future, and we see that it is so. You have seen the big Ferris Wheel1 in Chicago. The wheel revolves, and the little rooms in the wheel are regularly coming one after another; one set of persons gets into these, and after they have gone round the circle, they get out, and a fresh batch of people gets in. Each one of these batches is like one of these manifestations, from the lowest animal to the highest man. Nature is like the chain of the Ferris Wheel, endless and infinite, and these little carriages are the bodies or forms in which fresh batches of souls are riding, going up higher and higher until they become perfect and come out of the wheel. But the wheel goes on. And so long as the bodies are in the wheel, it can be absolutely and mathematically foretold where they will go, but not so of the souls. Thus it is possible to read the past and the future of nature with precision. We see, then, that there is recurrence of the same material phenomena at certain periods, and that the same combinations have been taking place through eternity. But that is not the immortality of the soul. No force can die, no matter can be annihilated. What becomes of it? It goes on changing, backwards and forwards, until it returns to the source from which it came. There is no motion in a straight line. Everything moves in a circle; a straight line, infinitely produced, becomes a circle. If that is the case, there cannot be eternal degeneration for any soul. It cannot be. Everything must complete the circle, and come back to its source. What are you and I and all these souls? In our discussion of evolution and involution, we have seen that you and I must be part of the cosmic consciousness, cosmic life, cosmic mind, which got involved and we must complete the circle and go back to this cosmic intelligence which is God. This cosmic intelligence is what people call Lord, or God, or Christ, or Buddha, or Brahman, what the materialists perceive as force, and the agnostics as that infinite, inexpressible beyond; and we are all parts of that.
