Who is God? The question perhaps would begin with the premise that you at least believe there is a god. So, who is He? Can anyone possibly answer this question? Well, of course. Now, I am not saying that I know who God is any more than any other God believing person, but I can certainly address the matter.
Consider the Gospel promise. That is, anyone who believes and is baptized will be saved and will receive the gift of the Holy Spirit (Acts ch 2 ver 38). Being baptized, however, is far more than getting dunked in water and proclaiming all is well. It is a sincere commitment; an honest desire; a true belief; a changed life. I say this because anyone who has obeyed the Gospel in baptism knows that the Holy Spirit does in fact come into them, but this can only be true for those who have chosen to do so on their own and for the right reason. Dunking your baby does not do anything.
So now we have our first insight into who God is, God is spirit. He knows our inner most thoughts and can dwell within us. “Here I am! I stand at the door and knock. If anyone hears my voice and opens the door, I will come in and eat with that person, and they with me.” (Rev ch3 ver 20).
Have you ever thought or heard “Could God be an alien?” Well, of course God is not an alien! Even if our existence on earth had something to do with some alien race, you still end up with the question “Where did we come from?” Any person, place or thing that we can perceive (outside of God) is “the created”. God is not “the created”, but rather “the Creator” (Gen ch 1). And in the book of Isaiah, ch 40 ver 28, it says: “Do you not know? Have you not heard? The LORD is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom.” and Isaiah ch 42 ver 5: “This is what God the LORD says— the Creator of the heavens, who stretches them out, who spreads out the earth with all that springs from it, who gives breath to its people, and life to those who walk on it:…”
Now we see also that God is everlasting. That is, God is eternal. He has existed forever and is the “creator”, not the “created”. I must admit, this is a difficult concept to grasp, at least for me. I understand what it means and what it says, but to fully grasp the concept is to me somehow deeply perplexing. It shutters me inside in a way I cannot explain. Perhaps it is the immensity of “forever”. Perhaps because it makes me realize how small each of us really is. Yet, God loves each of us in a way we cannot understand. “I am the Alpha and the Omega,” says the Lord God, “who is, and who was, and who is to come, the Almighty.” (Rev ch1 ver 8); “I am the Alpha and the Omega, the Beginning and the End. To the thirsty I will give water without cost from the spring of the water of life…” (Rev ch 21 ver 6).
