The Bible answers the question: Who is God?
God is a Spirit (John 4:24). He is One, but exists as three Persons—the Father, the Son, and the Holy Spirit (Matthew 3:16-17). God is infinite (1 Timothy 1:17), incomparable (2 Samuel 7:22), and unchanging (Malachi 3:6). He 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).
God is loving (Ephesians 2:4-5), just (Acts 17:31), truthful (John 14:6), and holy (1 John 1:5). He shows compassion (2 Corinthians 1:3), mercy (Romans 9:15), and grace (Romans 5:17). He is a righteous judge (Psalm 5:5) but He also offers forgiveness (Psalm 130:4) to those that ask.
God is the Creator of heaven and earth (Genesis 1:1; Psalm 146:6; Nehemiah 9:6). We cannot understand God apart from His works, because what God does flows from who He is. He actively sustains His creation (Colossians 1:17). He reveals His good will towards humans (Ephesians 1:11) which involves the redemption of man from the curse of sin and death (Galatians 3:13-14). He draws people to Him through the ministry of His Son Jesus Christ (John 6:44). He disciplines His children with love (Hebrews 12:6) and will also judge the evil doers (Revelation 20:11-15).
The Relationship with Him
God is our heavenly Father who loved us unto death. In the Person of the Son, God became incarnate (John 1:14) in order to bear the penalty of our sins, which is death. Thus, the Son of God is the “bridge” between God and man (John 14:6; 1 Timothy 2:5). It is only through Jesus that we can have peace (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.
Finally, if we wish to summarize who is God in one word, that word would be “God is love” (1 John 4:8). The Father showed us His infinite love on the cross when He offered His only begotten Son to redeem humans from death “For God so loved the world, that he gave his only begotten Son, that whosoever believes in him should not perish, but have everlasting life” (John 3:16).
