It's important for us to remember that Jesus said that Satan was the ruler of this world. When evil happens, it's not because God is absent but because Satan is the ruler here. For we Christians, Satan can kill the body but not the spirit.
The instances in the Bible where God made His presence known are few and far between. Sometimes, those instances weren't very pleasant. The murals in the nursery show the animals getting into the ark, not the people drowning.
