One of the questions that not only I but many people have when learning that God has a body of flesh and bones is, "how could God be omnipresent if he has a body of flesh and bones that can only be in one place at a time?". Yes, I believe God is omnipresent. But how could God be omnipresent if he is a being with a body of flesh and bones? Upon studying this over a period of time I came to realize that part of God's being is his glory. God is a being of light. If God were to appear to us in all his glory, we would see him as a being that emits light from his body. His light is greater that the light that shines from the sun at midday. This light is part of his being and his light fills the immensity of space. It is in this way that God is omnipresent. His glory is in all and throug-h all things. In a revelation to the Prophet Joseph Smith, we learn the following:
Doctrine and Covenants 88:1-13
1 Verily, thus saith the Lord unto you who have assembled yourselves together to receive his will concerning you:
2 Behold, this is pleasing unto your Lord, and the angels rejoice over you; the alms of your prayers have come up into the ears of the Lord of Sabaoth, and are recorded in the book of the names of the sanctified, even them of the celestial world.
3 Wherefore, I now send upon you another Comforter, even upon you my friends, that it may abide in your hearts, even the Holy Spirit of promise; which other Comforter is the same that I promised unto my disciples, as is recorded in the testimony of John.
4 This Comforter is the promise which I give unto you of eternal life, even the glory of the celestial kingdom;
5 Which glory is that of the church of the Firstborn, even of God, the holiest of all, through Jesus Christ his Son—
6 He that ascended up on high, as also he descended below all things, in that he comprehended all things, that he might be in all and through all things, the light of truth;
7 Which truth shineth. This is the light of Christ. As also he is in the sun, and the light of the sun, and the power thereof by which it was made.
8 As also he is in the moon, and is the light of the moon, and the power thereof by which it was made;
9 As also the light of the stars, and the power thereof by which they were made;
10 And the earth also, and the power thereof, even the earth upon which you stand.
11 And the light which shineth, which giveth you light, is through him who enlighteneth your eyes, which is the same light that quickeneth your understandings;
12 Which light proceedeth forth from the presence of God to fill the immensity of space—
13 The light which is in all things, which giveth life to all things, which is the law by which all things are governed, even the power of God who sitteth upon his throne, who is in the bosom of eternity, who is in the midst of all things.
God not only has a body of flesh and bones but he is a being of light, which light fills the immensity of space and in this way God is in all and through all things the light of truth. In this way he is omnipresent. Much like a light bulb is only in one place but the light it emits fills the entire room.
