45. God Is One, and the Lord Is God
On the basis of the quite ample number of passages from the Word presented in the preceding chapter, we can determine that the Lord is called Jehovah, the God of Israel and of Jacob, the Holy One of Israel, Lord and God, as well as King, [Jehovah’s] Anointed, and David, all of which enables us to see (though as yet through a kind of veil) that the Lord is God himself, the source and subject of the Word.
All the same, it is generally acknowledged everywhere in the whole world that God is one, and no one of sound reason denies this. What now remains to be done, then, is to support this from the Word and further, to show that the Lord is God.
 1. The following passages from the Word show that God is one.
Jesus said, “The first of all the commandments is ‘Hear, O Israel, the Lord our God, the Lord is one; therefore you are to love the Lord your God with all your heart and with all your soul.’” (Mark 12:29-30)
Hear, O Israel, Jehovah our God is one Jehovah; you are to love Jehovah your God with all your heart and with all your soul. (Deuteronomy 6:4-5)
Someone came to Jesus and said, “Good Teacher, what good thing should I do in order to have eternal life?” Jesus said to him, “Why do you call me good? No one is good except the one God.” (Matthew 19:16-17)
... so that all the kingdoms of the earth may acknowledge that you alone are Jehovah. (Isaiah 37:20)
I am Jehovah and there is no other. There is no God other than me. [I have prepared you] so that people will know from the rising of the sun to its setting that there is no God other than me. I am Jehovah and there is no other. (Isaiah 45:5-6)
Jehovah Sabaoth, God of Israel, dwelling between the angel guardians, you alone are God over all the kingdoms of the earth. (Isaiah 37:16)
Is there any God other than me? Or any other Rock? I do not know of one. (Isaiah 44:8)
Who is God, except Jehovah? Who is the Rock, if it is not our God? (Psalms 18:31)
 2. The following passages from the Word show that the Lord is God.
God is only among you, and there is no God except him. Surely you are a hidden God, O God of Israel, the Savior. (Isaiah 45:14-15)
Am I not Jehovah? And there is no God other than me. I am a just God, and there is no Savior other than me. Look to me so that you may be saved, all you ends of the earth, because I am God and there is no other. (Isaiah 45:21-22)
I am Jehovah, and there is no Savior other than me. (Isaiah 43:11)
I am Jehovah your God. You are to acknowledge no God other than me; there is no Savior other than me. (Hosea 13:4)
Thus says Jehovah the King of Israel, and Israel’s Redeemer, Jehovah Sabaoth: “I am the First and the Last, and there is no God other than me.” (Isaiah 44:6)
Jehovah Sabaoth is his name, and the Redeemer, the Holy One of Israel. He will be called the God of the whole earth. (Isaiah 54:5)
On that day Jehovah will become king over all the earth. On that day Jehovah will be one, and his name one. (Zechariah 14:9)
Since the Lord alone is Savior and Redeemer, and since it says that Jehovah and no one else is that one, it follows that the one God is no other than the Lord.
