Does God pick a side and back it when humans are in conflict with one another? Some say yes. Some say it's hard to answer no. Take World War II for example. Many people believe that God was on the side of the Allies. Many believe that the Allied defeat of Adolf Hitler and the Axis powers were at least influenced by God ensuring good in the world. Many would also say that further evidence of God's hand in the Allied victory in World War II was shown when the end result was the creation of a nation-state of Israel.
Convincing arguments, perhaps, of God intervening in a conflict, picking one side over the other, and influencing the outcome. But then there's the other side - people who question the level of providence with which God acts. There are two sides to every conflict - each believing that the other is wrong and they are right - believing this so passionately that there would be no conflict otherwise. I can make a moral judgment based on my cultural values or religious values, but those are my judgments to which one can negate my his or her respective values.
So, back to the question: Does God take sides? In the case of World War II, it's easy to say yes because we (the United States) won. And we believe freedom is a good thing. But as with the case of Islamic fundamentalism, everyone believes God is on their side. So, does the side supported by God win? Is that how we know?
Or does God simply look at us, and be with us, and be saddened by the fact that people wage war on one another? Or does what he can to minimize the damage?
Does he adamantly intervene for a cause that he supports? Or does God just shake his head and keep asking himself why can't we just get along?
