God Almighty has no need of your worship, nor indeed of anything else. Rather, it is you who needs to worship, for in truth you are sick. Worship is a sort of remedy for your spiritual wounds. If someone who is ill responds to a compassionate doctor who insists on his taking medicines that are beneficial for his condition by saying: "What need do you have of it that you are insisting in this way?" you can understand how absurd it would be.
