The self-existence of God proves that he always was, and evidently shows that he cannot cease to be. “He is, and was, and is to come.” His necessary existence comprehends a duration which has neither beginning, succession, nor end. He can have no succession in his duration, because wherever this is there must be priority, and wherever there is a priority there must be a beginning. He is in the complete possession of an endless life, all at once. He exists in one eternal _now_. He is unchangeable in his essence or manner of existence, so that no perfection can be added to him, nor any excellency taken from him, but he remains invariably the same. All natural perfections are essential to him as an infinite being, such as eternity, omnipotence, immensity, omniscience, spirituality, and immutability; and all moral perfections belong to him as a good Being, such as wisdom, holiness, justice, goodness, truth, faithfulness. These latter are communicable, because there are some rays of them in his creatures, but none of them in that transcendent degree that are in him, nor ever can be. The former we call his _natural_ and _incommunicable_ perfections, for the sake of distinction; though it is certain the latter are equally as natural to him, and incommunicable, in that infinite degree possessed by himself. God being unchangeable in his essence, must also be so in all his perfections, because they are no other than his essence, and are not distinguished in him, either from his essence, or from one another; but are one and the same Being, revealed and manifested to us, under various notions, which we call _attributes_, to help us the better to conceive of him, who are not able to apprehend what may be known of him, under any one name, or by any one act of our understanding. The combination of all his perfections renders him a glorious Being; and that fixed and invariable state of contentment and satisfaction, complacency and delight, which result from the secure possession and enjoyment of all that is good and desirable, or, in other words, of all possible excellencies and perfections in the highest degree, constitutes him infinitely blessed.
