But they consider themselves too weak for such an important task. They shudder to think about that very important task, that dreadful task to be God's mouth, and to speak it without their own thoughts. They say, O God, give me Thine word, because I have not. Please, instruct me, o God, and tell me what I must do. Isaiah, so much having need of God's instruction, also gets it.
All mankind is like grass.
In the morning, it is green and young, but in the evening it is cut off, or devoured by the beasts. All the goodliness of people, that is, all their beauty, is like the beauty of the flowers of the field. In the morning, they flourish, but in the evening, they come to an end. That is a lively picture of the human race. To say such things belongs to the charge of the true preachers, sent by God.
