God is thought to be eternal. Does this mean that he is timeless? Or is he, rather, omnitemporal? In this paper we want to show that God cannot be omnitemporal. Our starting point, which we take from Bernard Williams’ article on the Makropulos Case, is the intuition that it is inappropriate for persons not to become bored after a sufficiently long sequence of time has passed. If God were omnitemporal, he would suffer from boredom. But God is the greatest possible being and therefore cannot be bored. God, hence, is not omnitemporal. After the presentation of our argument, we address several objections by examining possible differences between human and divine persons.
