God is often conceived as the Supreme Being and principal object of faith. In theism, God is the creator and sustainer of the universe. In deism, God is the creator of the universe. In pantheism, God is the universe itself. Theologians have ascribed a variety of attributes to the many different conceptions of God. Common among these are omniscience, omnipotence, omnipresence, omnibenevolence, divine simplicity, and eternal and necessary existence. Monotheism is the belief in the existence of one God or in the oneness of God. God has also been conceived as being incorporeal, a personal being, the source of all moral obligation, and the "greatest conceivable existent". this deity is called Aten. In the Hebrew Bible "I Am that I Am", and the "Tetragrammaton" YHVH are used as names of God, while Yahweh, and Jehovah are sometimes used in Christianity as vocalizations of YHVH. In Arabic, the name Allah is used, and because of the predominance of Islam among Arab speakers, the name "Allah" has connotations with Islamic faith and culture. Muslims regard a multitude of titular names for God, while in Judaism it is common to refer to God by the titular names Elohim or Adonai, the latter of which is believed by some scholars to descend from the Egyptian Aten. In Hinduism, Brahman is often considered a monistic deity. Other religions have names for God, for instance, Baha in the Bahá'í Faith, Waheguru in Sikhism, and Ahura Mazda in Zoroastrianism.
The many different conceptions of God, and competing claims as to God's characteristics, aims, and actions, has led to the development of ideas of Omnitheism, Pandeism, or a Perennial philosophy, wherein it is supposed that there is one underlying theological truth, of which all religions express a partial understanding, and as to which "the devout in the various great world religions are in fact worshipping that one God, but through different, overlapping concepts or mental images of him."
