People often ask, or at least wonder, why God doesn't prevent the many disasters that seem to be occurring with increasing frequency. Why didn't he stop the earthquake that hit Japan? Why doesn't he stop the tornadoes? Why doesn't he stop the floods and the hurricanes? There are two reasons.
    Have you seen the classic science fiction movie “The Forbidden Planet”? In that film, a violent monster is killing people. When Walter Pigeon tells Robby the Robot to kill the monster, Robby shorts out. That is because his programming won't allow him to harm humans and he knows that the monster is coming from Walter Pigeon's subconscious mind so the only way to stop the monster is to kill Pigeon. The same thing applies here. God could stop the storms, earthquakes, tornadoes, etc., but only by killing us. 
    It is our negative, angry and violent thoughts that create those storms. We are doing it to ourselves without really realizing it. When we have strong thoughts accompanied by strong emotions, we generate a kind of energy vortex. Those vortexes of angry, hateful energy combine with others, and those combine with even more: there is plenty of these negative energy vortexes to go around. And when the vortex gets big enough and strong enough, it becomes something physical: a storm, an earthquake, a war, etc. The only way God can stop this is to stop us from generating those thoughts.
    Second, if you tell a kid to stay away from the hot stove or the barbecue grill so he won't get burned, but he insists on getting near it and touching it anyway, the solution is to let him get burned a little and learn his lesson the hard way. You don't put oven mitts on his hands so he can touch hot things without getting burned. He would not learn if you did that. Likewise, we all need to learn that our erroneous behavior has consequences. If God prevented the consequences, we would not learn from our mistakes.
    So if we want to prevent disasters, we have to do it ourselves by controlling our thoughts and behavior.
