I wonder if we just make ourselves more vulnerable when we do such things. We know that evil is all around us, but we continue to give evil the targets it needs. That was the perfect target, for materialism has no place in eternity. We must be very sure of one thing. God does not make these things happen.
Sin is the result of human agendas.
God does not bring about death. In fact, he abhors death so much that He sent His Son to conquer it. He saves us from death. We must start to question why someone would qualify life as to think it worthless and easy to destroy as was done so recently. The people in the plane and buildings were expendable because of the agenda of others.
