Across cultures humans have addressed a supreme reality believed to create, sustain, and judge the world. That reality is called God in English-speaking monotheistic contexts. The concept varies in emphasis yet centers on ultimate power, knowledge, and moral authority.

Classical theism describes God as eternal, omnipotent, omniscient, and perfectly good. Personalist traditions emphasize relationship, prayer, and covenant. Mystical paths stress ineffable unity beyond all images. Arguments for God’s existence draw on cosmology, morality, religious experience, and design; counter-arguments cite evil, divine hiddenness, and the success of naturalistic explanation.

Belief in God shapes ethics, politics, art, and personal identity for billions. Atheism and agnosticism define themselves in relation to the same concept. Language about God remains both the most exalted and the most contested in human speech.
