The One And Only True God

To those who are dealings with worshiping idols; Hear and listen to what God
said about this issue:

(Isaiah 44:16-20)
Half of the wood he burns in the fire; over it he prepares his meal,
   he roasts his meat and eats his fill. He also warms himself and says,
   "Ah! I am warm; I see the fire." From the rest he makes a god,
    his idol; he bows down to it and worship. He prays to it and says,
   "Save me! You are my god!"
They know nothing, they understand nothing, their eyes are plastered
over so they cannot see, and their minds closed so they cannot understand.
No one stops to think, no one has the knowledge or understanding to say,
"Half of it I used for fuel; I even baked bread over its coals, I roasted
 meat and I ate. Shall I make a detestable thing from what is left?
 Shall I bow down to a block of wood?"
 Such a person feeds on ashes; a deluded heart misleads him;
 he cannot save himself, or say, "Is not this thing in my right hand a lie?"

Is not God in the heights of heaven? And see how lofty are the highest stars!
Lift up your eyes and look to the heavens:
Who created all these? He who brings out the starry host one by one and
calls forth each of them by name. Because of his great power and mighty strength,
not one of them is missing.  (Job 22:12) (Isa.40:25-26)

The Lord is the everlasting God, the Creator of the ends of the earth. 
(Isa.40:28)

"To whom will you compare me? Or who is my equal? says the Holy One. 
  (v.25)

I am the first and I am the last; apart from me there is no God. (Isa.44:6,8)
Is there any God besides me? No, there is no other Rock; I know not one.

I am the LORD; that is my name! I will not yield my glory to another or my praise
to idols. (Isa.42:8)

For God is a consuming fire, a jealous God, He wanted us to worship Him only.
(Deuteronomy 4:24)
