The only answer to this, and it isn't an entire answer, said Father Travis, is that God made human beings free agents. We are able to choose good over evil, but the opposite too. And in order to protect our human freedom, God doesn't often, very often at least, intervene. God can't do that without taking away our moral freedom. Do you see? No. But yeah. The only thing that God can do, and does all of the time, is to draw good from any evil situation.
