WHO IS GOD?
This article is adapted from Jason’s book The Bible’s Answers to 100 of Life’s Biggest Questions.
There is so much to write about God, and yet, so much we can’t even fathom. Nevertheless, God has revealed enough in His creation (general revelation) and in His Word (special revelation) to help us understand who He is!
The trinity (or tri-unity (3-in-1) of the Godhead) is an important doctrine to know about the nature of God. Christians are not tri-theistic (belief in three gods), but are monotheistic (belief in one God). Christianity teaches that God is one in nature (Deut. 6:4; cf. Isa 44:6-8)—and eternally revealed in three distinctive (yet united) personhoods (Father, Son, and Holy Spirit). Each member of the trinity has distinct roles, but share a unique, yet eternally equal relation within the Godhead.
The Self-Existence of God
To say God is Self-Existent is to mean He is absolutely independent of anyone or anything. The phrase comes from the word aseity, which literally means “of oneself.” The Self-Existence of God is recorded by Moses in Exodus 3:14, when God announced from the burning bush, “I AM THAT I AM.”
The Self-Sufficiency of God
Since God exists eternally and independently of everything, it is reasonable to deduce that He is also self-sufficient. The self-sufficiency of God is supported by various passages in the Bible. The prophet Isaiah writes, “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” (40:28). Elsewhere, Isaiah records these words of God: “I am the Lord; that is my name! I will not give my glory to another or my praise to idols.”
Allow us to offer three more properties about God from Scripture. The first is the omnipresence of God. God simply is infinite and presently involved everywhere in His creation all at once. That is, there is nowhere God is not present in His creation. Isaiah records, “The Lord is the everlasting God, the Creator of the ends of the earth” (40:28). David pondered, “Where shall I go from your Spirit? Where can I flee from your presence” (Ps. 139:7; cf. Jer. 23:23-24)? There is absolutely no limitation to the presence of God. He is not limited to the boundaries of the universe.
The second is the omniscience of God. Scripture also states that God “knows the end from the beginning” (Isa. 46:10). David adds, “[God’s] understanding has no limit” (Ps. 147:5). Job sarcastically asks, “Can anyone teach knowledge to God” (Job 21:22)?
The third is the omnipotence of God. God has the absolute power to do all things that He wills to do. Abraham asks this rhetorical question, “Is anything too hard for the Lord” (Gen. 18:14)? David proclaims, “The earth is the Lord’s, and everything in it, the world, and all who live in it” (Ps. 24:1). Since God created the universe, it follows that He is the rightful owner as well as the sovereign ruler over all things. There is nothing in existence that exists without the sovereign rule of God or is outside His knowledge.

Attempts to grasp these admittedly incomprehensible truths about God can really make our heads spin. This shows us how unimaginably big, powerful, and good He is. He is worthy of our trust and devotion!
