God discloses who He is

Isaiah: 44. 24 “This is what the Lord says— your Redeemer, who formed you in the womb: I am the Lord, the Maker of all things, who stretches out the heavens, who spreads out the earth by myself, 25. who foils the signs of false prophets and makes fools of diviners, who overthrows the learning of the wise and turns it into nonsense, 26. who carries out the words of his servants and fulfills the predictions of his messengers, who says of Jerusalem, ‘It shall be inhabited,’ of the towns of Judah, ‘They shall be rebuilt,’ and of their ruins, ‘I will restore them,’ 27. who says to the watery deep, ‘Be dry, and I will dry up your streams,’ 28. who says of Cyrus, ‘He is my shepherd and will accomplish all that I please; he will say of Jerusalem, “Let it be rebuilt,” and of the temple, “Let its foundations be laid.”‘ – Bible Offline
