God never promises exemption. He does promise companionship, which is better. He does not promise do deliver you or me or any other individual from pain, sorrow, or economic disaster, but He does give assurance the He will help us through and that there will be compensations. "I will not leave you comfortless, I will come to you." These are the words of Jesus.
She can live through it, because we do not hold the belief that this earth is a realm of misery where man is doomed to destruction. We do not think that tragedy is our natural fate and we do not live in chronic dread of disaster. We do not expect disaster until we have specific reason to expect it - and when we encounter it, we are free to fight it. It is not happiness, but suffering that we consider unnatural. It is not success, but calamity that we regard as the abnormal exception in human life.
