The post is a runner who is carrying letters, and is chosen for his speed. Job’s days seem pointless and rush past accomplishing nothing.
How greatly mistaken the Christian can be at his gloomiest moments. All these words of Job and all his trials were being recorded and would be preserved in God’s word for future generation. They would teach believers how to avoid these mistakes, and set before us a man who was pressed beyond measure, and yet did not deny his God. Job by his patience was proving the powers of darkness to be wrong about the tenacity of faith, but all this was hidden from him for the moment.
