Isaiah 45:22

Look unto Me and be ye saved, all the ends of the earth, the turning to the Lord in true repentance being followed by the imparting of salvation, or, more exactly, as His call produces repentance, it also works faith, thereby granting salvation full and free, and His call goes out to all men: For I am God, and there is none else, a declaration which is repeated time and again in order to convince the idolaters, to cause them to accept the true God.
