“You are My witnesses,” says the LORD, “and 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, nor shall there be after Me.  I, even I, am the LORD, and besides Me there is no savior.  I have declared and saved, I have proclaimed, and there was no foreign god among you; therefore you are My witnesses,” says the LORD, “that I am God. Indeed before the day was, I am He; and there is no one who can deliver out of My hand; I work, and who will reverse it”

Isaiah 43:10-13 (NKJV)
