God is immutable, which means that He does not and cannot change. “I am the Lord; I change not,” He declared in the book of Malachi. God cannot change because He is perfect. True and absolute perfection is inconsistent with change. If a being changed for the better, then he was not perfect before; and if he changed for the worse, then he was not perfect afterwards. Furthermore, circumstances do not alter God’s nature. Since He is the only self-existent being, He was perfect before anything else was created. He did not create the world because He was lacking in some regard. The Father, the Son and the Holy Spirit enjoyed perfect and infinite communion and unity in eternity, and stood in need of nothing. Creation did not change God.

God is immense or omnipresent, which is the theological way of saying that He cannot be limited with regard to space. At the dedication of the temple, Solomon said, “But will God indeed dwell on the earth? behold, the heaven and heaven of heavens cannot contain thee; how much less this house that I have builded?” If the heaven of heavens cannot contain or hold God’s infinite nature, then it is clear that nothing else in creation can do so. God does not have to move from place to place, but is in all places at once. “If I ascend up into heaven, thou art there: if I make my bed in hell, behold, there art there”       (Ps. 139.8). The psalmist recognized that God’s vast nature fills all, whether with regard to this world or the next. It is true that the human nature of the Christ was as limited with regard to space as are we, but the divine nature of the Son was as infinite as the other Persons in the Godhead. This wonderful fact is illustrated by the statement of our Lord, “And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven” (Jn. 3.13). Even when the Son of man was here upon the earth, He retained in His divine nature all the perfection of the Godhead, including omnipresence.

God is eternal, which means that He has no limits with regard to time. The minutes do not tick off with God, for He has said that His name is I AM, which declares His eternal nature. His name is not “I Was” or “I Will  Be,” but I AM. It is in the present tense because the passage of time is of no consequence to God. Our Lord said, “Before Abraham was, I am.” Grammatically that is incorrect, but the words of finite men cannot adequately express the infinity of God. The Son of God was the great I AM before the time of Abraham. Even in the past, He is, as hard as that is for us to comprehend. His infinite nature cannot be measured in terms of time any more than it can be measured in terms of space. Peter tells us that thousand years is to God as if it were a day (and he just as easily could have said a minute or a second).
