This is a response for Reniaa, Pilchard, and any other Jehovah's Witnesses or Unitarians (Non-Trinitarians) who may be reading this. First, I will lay out a very short (but strong) case for believing that the Bible teaches that Jesus is the One True God by Nature, along with The Father.
Then (perhaps tomorrow) I will attempt to respond to every single point made by Reniaa and Pilchard in this thread.
When we make claims about what the Bible says about the Nature of God, and whether or not Jesus has the Nature of God, and what that means, we need to define our terms. For example, when I read the posts of Reniaa and Pilchard, I still cannot figure out exactly what they mean when they say that Jesus is "a god" and what they mean when they say The Father is "The God." What exactly do you mean? What exactly is the difference between "The God" [Father] and "a god" [The Son] and where does the Bible actually say Jesus is "a god" (besides the highly-disputed John 1:1, which no scholar or expert that I know says it should be rendered "a god")?
My Short Case for The Deity of Christ:
The Book of Isaiah (as well as Exodus and Deuteronomy) clearly, unambiguously teach that there is Only One True God by Nature, and His Name is YHWH [Jehovah/Yahweh]:
Isaiah 46:5, 9 (ESV): "To whom will you liken me and make me equal, and compare me, that we may be alike? ... for I am God, and there is no other; I am God, and there is none like me,
Isaiah 44:6-8 (ESV): Thus says the LORD, the King of Israel and his Redeemer, the LORD of hosts: "I am the first and I am the last; besides me there is no god. Who is like me? ... And you are my witnesses! Is there a God besides me? There is no Rock; I know not any."
Isaiah 45:5-6 (ESV): I am the LORD, and there is no other, besides me there is no God; ... there is none besides me; I am the LORD, and there is no other.
Isaiah 45:21-24 (ESV): ... And there is no other god besides me, a righteous God and a Savior; there is none besides me. "Turn to me and be saved, all the ends of the earth! For I am God, and there is no other. By myself I have sworn; from my mouth has gone out in righteousness a word that shall not return: 'To me every knee shall bow, every tongue shall swear allegiance.' "Only in the LORD, it shall be said of me, are righteousness and strength; ...
Deuteronomy 32:39 (ESV): "'See now that I, even I, am he, and there is no god beside me; ...
Deuteronomy 6:13-15 (ESV): It is the LORD your God you shall fear. Him you shall serve and by his name you shall swear. You shall not go after other gods, the gods of the peoples who are around you--for the LORD your God in your midst is a jealous God--lest the anger of the LORD your God be kindled against you, and he destroy you from off the face of the earth.
Exodus 20:3, 5 (ESV): "You shall have no other gods before me. ... You shall not bow down to them or serve them, for I the LORD your God am a jealous God, ...
Exodus 34:14 (ESV): (for you shall worship no other god, for the LORD, whose name is Jealous, is a jealous God),
The New Testament teaches the same thing:
Mark 12:29, 32 (ESV): Jesus answered, "The most important is, 'Hear, O Israel: The Lord our God, the Lord is one. ... And the scribe said to him, "You are right, Teacher. You have truly said that he is one, and there is no other besides him.
Matthew 4:10 (ESV): Then Jesus said to him, "Be gone, Satan! For it is written, "'You shall worship the Lord your God and him only shall you serve.'"
James 2:19 (ESV): You believe that God is one; you do well. ...
Romans 3:30 (NIV): ... there is only one God ...
But, when you come to the New Testament teachings about Christ, you find out that it says Jesus is God (John 20:28; 2 Peter 1:1; Titus 2:13; John 1:18), and that He has the same Nature as God (John 1:1; Colossians 2:9), that He has always existed with The Father (John 1:1-3), and that Jesus must be worshiped just as The Father is worshiped (John 5:23; Hebrews 1:6; Philippians 2:9-11; Revelation Chapter 5), and also that The Son is exactly like The Father (Hebrews 1:3).
How does the New Testament's teachings about Jesus harmonize with those verses in Isaiah, Deuteronomy, and Exodus?
