Who is God? – The Fact
The fact of God’s existence is so conspicuous, both through creation and through man’s conscience, that the Bible calls the atheist a “fool” (Psalm 14:1). Accordingly, the Bible never attempts to prove the existence of God; rather, it assumes His existence from the very beginning (Genesis 1:1). What the Bible does is reveal the nature, character, and work of God.
Who is God? – The Definition
Thinking correctly about God is of utmost importance because a false idea about God is idolatry. InPsalm 50:21, God reproves the wicked man with this accusation: “You thought I was altogether like you.” To start with, a good summary definition of God is “the Supreme Being; the Creator and Ruler of all that is; the Self-existent One who is perfect in power, goodness, and wisdom.”
Who is God? – His Nature
We know certain things to be true of God for one reason: in His mercy He has condescended to reveal some of His qualities to us. God is spirit, by nature intangible (John 4:24). God is One, but He exists as three Persons—God the Father, God the Son, and God the Holy Spirit (Matthew 3:16-17). God is infinite (1 Timothy 1:17), incomparable (2 Samuel 7:22), and unchanging (Malachi 3:6). God exists everywhere (Psalm 139:7-12), knows everything (Psalm 147:5;Isaiah 40:28), and has all power and authority (Ephesians 1;Revelation 19:6).
Who is God? – His Character
Here are some of God’s characteristics as revealed in the Bible: God is just (Acts 17:31), loving (Ephesians 2:4-5), truthful (John 14:6), and holy (1 John 1:5). God shows compassion (2 Corinthians 1:3), mercy (Romans 9:15), and grace (Romans 5:17). God judges sin (Psalm 5:5) but also offers forgiveness (Psalm 130:4).
Who is God? – His Work
We cannot understand God apart from His works, because what God does flows from who He is. Here is an abbreviated list of God’s works, past, present, and future: God created the world (Genesis 1:1;Isaiah 42:5); He actively sustains the world (Colossians 1:17); He is executing His eternal plan (Ephesians 1:11) which involves the redemption of man from the curse of sin and death (Galatians 3:13-14); He draws people to Christ (John 6:44); He disciplines His children (Hebrews 12:6); and He will judge the world (Revelation 20:11-15).
Who is God? – A Relationship with Him
In the Person of the Son, God became incarnate (John 1:14). The Son of God became the Son of Man and is therefore the “bridge” between God and man (John 14:6;1 Timothy 2:5). It is only through the Son that we can have forgiveness of sins (Ephesians 1:7), reconciliation with God (John 15:15;Romans 5:10), and eternal salvation (2 Timothy 2:10). In Jesus Christ “all the fullness of the Deity lives in bodily form” (Colossians 2:9). So, to really know who God is, all we have to do is look at Jesus.
