The fourth step in escaping the fall is to know the frailty of man. Enosh is another interesting name in Genesis 4. Enosh means "frail, mortal man." This implies that to escape from walking on the path of the fall, we need to know the frailty of man. We need to know that man is nothing and can break, just as a glass cup breaks easily. This is frailty. Man is frail. Some people do not know themselves. They think that they are smart, wise, and strong, when in fact they have nothing of which to boast. When a car hits a man, he is as fragile as a glass cup. When he is infected with tuberculosis, he must lie down. He may even die from tuberculosis. Man's life is frail. Man's name is Abel, but man's name is also Enosh. Abel means that man is vain, but Enosh means that man is frail. People who dream about their life should wake up. Man is not strong. Man will collapse when he is sick, and he will die if a car hits him. A wife can collapse when she is mad at her husband. She can even get ulcers because of her anger. A person can live to be one hundred years at most. The Chinese say that few can live to the age of seventy. Being fifty years old is not yet the twilight hour, but it is already four o'clock in the afternoon. Some people are at eight or nine o'clock in the evening. There is a hymn that says, "Swift to its close ebbs our life's little day" (Hymns, #370, stanza 2). People must wake up from their dreams, because human life is vain and frail. In order to escape the fall, we must realize the meaning of human life. Those who continue in the fall do not know their own human life. In chapter 4 those who were delivered out of the fall knew that human life is vain and frail.
