To be satisfied in God is the highest difficulty in the whole world, and yet most easy to be done. To make it possible that we should be satisfied in God was an achievement of infinite weight, before it was attempted, and the most difficult thing in all worlds before it was achieved. For we naturally expect infinite things of God: and can be satisfied only with the highest reason. So that the best of all possible things must be wrought in God, or else we shall remain dissatisfied: But it is most easy at present, because God is. For God is not a being compounded of body and soul, or substance and accident, or power and act, but is all act; pure act, a Simple Being whose essence is to be, whose Being is to be perfect so that He is most perfect towards all and in all. He is most perfect for all and by all. He is in nothing imperfect, because His Being is to be perfect. It is impossible for Him to be God and imperfect: and therefore do we so ardently and infinitely desire His absolute perfection.
