in orthodox christianity we believe in God's supernatural miracles. there are occasions when God intervenes. but often people rely so heavily in God's intervention that they disregard their own actions. and as a result, evil things happen because of our actions and then we blame God for not interventing. for example, slavery. people force others to become slaves, an evil action. and then we blame God for slavery??? for ''allowing'' it and not stop it miraculously??? shouldn't our OWN actions become the miracle???
I would agree with this overall, although it seems part of the problem is that there are stories of God intervening numerous times. But then, there are many other times where God does not intervene, yet we're supposed to accept that "God moves in mysterious ways."
Evil things happen because many humans have a propensity towards evil and they commit evil deeds. But good people are often bound by God's law and severely restricted as to what they can actually do to fight evil.
I can see where some people might feel that the society around them is so heavily inundated with "evil" that they feel utterly powerless to do anything about it. People are just supposed to have faith that God will punish evildoers in the end, but even if that's true, it doesn't do much to help those who are having to endure the evil that takes place. It's easy for God to sit up there and watch everyone suffering, but for those of us down here, it's not that easy.
There were probably numerous evils which might have been prevented or lessened if God had made a few subtle manipulations or slight changes in events. For example, there were numerous assassination attempts on Hitler throughout his reign, yet he survived them all. He took it as a sign of "divine intervention," but others might just say it was "bad luck." Could God have intervened and turned the course of history, saving tens of millions of lives? Or was it all "meant to happen"? If it was "meant to happen," can God be blamed for that, since it was part of His plan all along?
