What is the Almighty, that we should serve him? "Who is Jehovah," said Pharaoh to Moses, "that I should obey his voice? I know not Jehovah" (Exodus 5:2). So the ungodly in Job's time. They pretend to have no knowledge of God, no sense of his claims upon them, no internal consciousness that they are bound to worship and obey him.
They are agnostics of a pronounced type, or at least they profess to be such. What profit, they ask, should we have, if we pray to him? Expediency is everything with them. Will serving God do them any good?
Will it advance their worldly interests? Persuade them of that, and they will be willing to pay him, at any rate, a lip-service. But, having prospered so long and so greatly without making any religious profession, they see no reason to believe that they would prosper more if they made one.
