This is an important question because it is important to get the definition right.  A false idea about God ultimately leads to idolatry (if worshipped) or a straw man attack (if attacked).

The Biblical definition of God can only be described by God’s attributes, since God is Spirit (John 4:24).  This tells us that God exists non-materially, that is, God is not made of matter.  We can know certain things about God’s existence because, in God’s mercy, He has condescended to our level to reveal some of His attributes to us.  The following are a list of God’s attributes, as revealed in God’s Word, the Bible:

  • Eternal (Deuteronomy 33:27, Isaiah 40:28, Habakkuk 1:12, Romans 1:20, Revelation 1:8, 22:13)
  • Creator (See this page for a TON of references)
  • Righteous (Deuteronomy 32:4, Psalm 119:137, Isaiah 45:21, John 17:25
  • Just (Job 37:23, 2 Timothy 4:8, Revelation 15:3)
  • Holy (Psalm 22:3, Isaiah 43:15, Isaiah 57:15, John 17:11,  1 Peter 1:16, Revelation 4:8)
  • Omniscient (Psalm 147:5, Isaiah 40:28,  Romans 11:33-36, 1 John 3:20)
  • Omnipotent (Job 42:2, Psalm 147:5, Jeremiah 32:27, Isaiah 40:28,  Matthew 19:26, Romans 1:20)
  • Omnipresent (Psalm 139:7-10, Proverbs 15:3, Jeremiah 23:24)
  • Sovereign over all Creation (Exodus 4:11, Isaiah 45:21, Isaiah 46:9-10, Daniel 4:34-35, Romans 11:33-36, Ephesians 1:11, Job 42:2)
  • Cannot do anything outside His own nature (Numbers 23:19,
    Hebrews 6:18, 1 Samuel 15:29 )
  • Does not change (1 Samuel 15:29, Malachi 3:6, James 1:17)
  • Cannot tempt us (James 1:13)
  • Enables believers to resist evil (1 Corinthians 10:13)

It is also important to note that God exists as a trinity of persons.
