God - Who is he?
God is the principal or sole deity in religions and other belief systems that worship one deity.
God is most often conceived of as the creator and overseer of the universe. Theologians have ascribed a variety of attributes to the many different conceptions of God. The most common among these include omniscience, omnipotence, omnipresence, omnibenevolence (perfect goodness), divine simplicity, jealousy, and eternal and necessary existence. God has also been conceived as being incorporeal, a personal being, the source of all moral obligation, and the "greatest conceivable existent". These attributes were all supported to varying degrees by the early Jewish, Christian and Muslim theologian philosophers, including Augustine of Hippo, Al-Ghazali, and Maimonides. Many notable medieval philosophers developed arguments for the existence of God, attempting to wrestle with the apparent contradictions implied by many of these attributes.
Names of God
Conceptions of God can vary widely, but the word God in English—and its counterparts in other languages, such as Latinate Deus, Greek Θεός, Slavic Bog, Sanskrit Ishvara, or Arabic Allah—are normally used for any and all conceptions. The same holds for Hebrew El, but in Judaism, God is also given a proper name, Yahweh, harking back to the religion's henotheistic origins. God may also be given a proper name in monotheistic currents of Hinduism which emphasize the personal nature of God, with early references to his name as Krishna-Vasudeva in Bhagavata or later Vishnu and Hari, or recently Shakti. In the Bible, when the word "Lord" is in all capitals, it signifies that the word represents the personal Hebrew name of god, Yahweh.
It is difficult to draw a line between proper names and epitheta of God, such as the names and titles of Jesus in the New Testament, the names of God in the Quran, and the various lists of thousand names of God and List of titles and names of Krishna in Vaishnavism
Conceptions of God
Conceptions of God vary widely. Theologians and philosophers have studied countless conceptions of God since the dawn of civilization. The Abrahamic conceptions of God include the trinitarian view of Christians, the Kabbalistic definition of Jewish mysticism, and the Islamic concept of God. The dharmic religions differ in their view of the divine: views of God in Hinduism vary by region, sect, and caste, ranging from monotheistic to polytheistic; the view of God in Buddhism is almost non-theist. In modern times, some more abstract concepts have been developed, such as process theology and open theism. Conceptions of God held by individual believers vary so widely that there is no clear consensus on the nature of God. The contemporaneous French philosopher Michel Henry has however proposed a phenomenological approach and definition of God as phenomenological essence of Life.
Existence of God
Many arguments for and against the existence of God have been proposed and rejected by philosophers, theologians, and other thinkers. In philosophical terminology, such arguments concern schools of thought on the epistemology of the ontology of God.
There are many philosophical issues concerning the existence of God. Some definitions of God are sometimes nonspecific, while other definitions can be self-contradictory. Arguments for the existence of God typically include metaphysical, empirical, inductive, and subjective types, while others revolve around holes in evolutionary theory and order and complexety in the world. Arguments against the existence of God typically include empirical, deductive, and inductive types. Conclusions reached include: "God exists and this can be proven"; "God exists, but this cannot be proven or disproven" (theism in both cases); "God does not exist" (strong atheism); "God almost certainly does not exist" (de facto atheism); and "no one knows whether God exists" (agnosticism). There are numerous variations on these positions.
A recent argument for the existence of God is intelligent design, which asserts that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection." It is a modern form of the traditional argument from design, modified to avoid specifying the nature or identity of the designer. Its primary proponents, all of whom are associated with the Discovery Institute, believe the designer to be the Abrahamic God.
