The only true God

A selection of verses showing that the God of the Bible is the only true God.

Through the prophet Isaiah, God challenges the idols to foretell the future as he does:

Isaiah 41 verses 21 - 24

21 Produce your cause,” says the LORD. 
“Bring out your strong reasons!” says the King of Jacob. 
22 “Let them announce and declare to us what will happen! 
Declare the former things, what they are, 
that we may consider them, and know the latter end of them; 
or show us things to come. 
23 Declare the things that are to come hereafter, 
that we may know that you are gods. 
Yes, do good, or do evil, 
that we may be dismayed, 
and see it together. 
24 Behold, you are nothing, 
and your work is nothing. 
He who chooses you is an abomination. 

Later in Isaiah's prophecy, God reminds him that he can foretell the future:

Isaiah 42 verse 9

9 Behold, the former things have happened 
and I declare new things. 
I tell you about them before they come up.” 

God says that the fact that he has foretold the Jews' history is evidence that he is God:

Isaiah 43 verses 9 - 12

9 Let all the nations be gathered together, 
and let the peoples be assembled. 
Who amongst them can declare this, 
and show us former things? 
Let them bring their witnesses, that they may be justified, 
or let them hear, and say, “That is true.” 
10 “You are my witnesses,” says the LORD, 
“With my servant whom I have chosen; 
that you may know and believe me, 
and understand that I am he. 
Before me there was no God formed, 
neither will there be after me. 
11 I myself am the LORD. 
Besides me, there is no saviour. 
12 I have declared, I have saved, and I have shown, 
and there was no strange god amongst you. 
Therefore you are my witnesses”, 
says the LORD, “and I am God. 

Isaiah 45 verses 20 - 22

20 “Assemble yourselves and come. 
Draw near together, you who have escaped from the nations. 
Those have no knowledge who carry the wood of their engraved image, 
and pray to a god that can’t save. 
21 Declare and present it. 
Yes, let them take counsel together. 
Who has shown this from ancient time? 
Who has declared it of old? 
Haven’t I, the LORD? 
There is no other God besides me, a just God and a Saviour. 
There is no one besides me. 
22 “Look to me, and be saved, all the ends of the earth; 
for I am God, and there is no other. 

Jesus says that our long-term future depends on us knowing the only true God:

John 17 verse 3

3  This is eternal life, that they should know you, the only true God, and him whom you sent, Jesus Christ. 

The apostle Paul tells the Corinthians that there is one God and one Lord Jesus Christ:

1 Corinthians 8 verse 6

6 yet to us there is one God, the Father, of whom are all things, and we for him; and one Lord, Jesus Christ, through whom are all things, and we live through him.
