Why Call Jesus God?
John 1:1-4,14;Colossians 1:15-19;Hebrews 1:1-4 He is Creator
Psalm 90:1-2 Being Creator, He is before time and thus eternal Micah 5:2 cf Matthew 2:1-6 see also Hebrews 7:1-3;13:8;1 John 1:1-3;5:20-22 (Isaiah 57:15)
Cf Revelation 1:8,11;21:6
This also shows us that the Son of God has no beginning. He is the beginning. He is timeless and eternal.
John 1:1-4;1 John 1:1-3;5:20-22 cf Genesis 2:7 He is life Deuteronomy 32:39-41
He is the JEHOVAH, the I AM Isaiah 40:3 (Here He is explicitly called God.) Matthew 3:1-3;John 1:19-34 cf John 8:58
He is Savior Matthew 1:21;Luke 1:47;2:11;John 4:42;Acts 5:31;13:23;Ephesians 5:23;Philippians 3:20;1 Timothy 1:1;4:10;2 Timothy 1:10;Titus 1:1-4;2:10-15;3:4-6;2 Peter 1:1,11;2:20;3:2,18;1 John 4:14;Jude 1:25
2 Samuel 22:3;Psalm 106:21;Isaiah 43:3,11;45:21-22;49:25-26;60:15-16;Hosea 13:4
These texts show us the following: there is only one Savior, God is that Savior, Jesus is that Savior. Seeing there is only one Savior, who is God, and that Jesus is our Savior, it follows that Jesus is God.
God knows all things. This is an attribute that belongs to God alone. Isaiah 46:8-11 cf John 21:17;Hebrews 4:12-13;
Scripture calls Him the unchanging, eternal God. Hebrews 1:8-12 cf Psalm 102:24-27 and Malachi 3:6;Hebrews 13:8
He is the Lord from Heaven 1 Corinthians 15:44-49
He is omnipresent John 1:18;3:13
He is almighty Genesis 17:1;18:14 cf Revelation 1:8,11;(19:6-16)Here we see that the Lamb is the almighty God, who is King of kings.
He is the Son of God and one with the Father. John 1:1-3,14;10:27-30;14:9;Philippians 2:5-8
Why Is This Doctrine Important?
Mediator- 1 Timothy 2:5-6 cf Galatians 3: The only way that our mediator could truly understand the way of God, represent God (John 1:18), accurately convey the heart and will of God (John 1:1-3,14;),and reconcile man to God (2 Corinthians 5:17-21), He must be God.
Savior-If Jesus is not God, He cannot save us. Only God is Savior Isaiah 45:21-22 cf Titus 2:11-14If Jesus is not God, we have no hope of future salvation at His return.
Worship- If Jesus is not God, He cannot rightfully be worshiped. No mere man is worthy of worship.
Service- The exalted Christ is the One Who is to be served and obeyed, not some mere human who deserves no honor and obedience as God deserves. Philippians 2:5-16
In short, this truth affects the whole of the Christian experience.
