Jesus while here on earth was with his disciples in a boat. He was asleep during a strong storm. His disciples were concerned about perishing. The anxiously awakened him. With that he roused himself and rebuked the winds and said to the sea hush. The wind abated, a great calm set in. What Jesus did then, he will do on a grand scale. Not only will he bring an end too natural disasters, he will also bring an end to all human suffering. Psalms 72:7,8 jw.org
