Abstract
God is usually taken to be a necessarily existing being who is unsurpassably powerful, knowledgeable and good. Theism is conceptualized in a single being that is monotheism in some religions and polytheism that is more than one being in some others. Yet some others see theism in everything of human concern that is pantheism. The doctrine of God is strong-minded by means of the religious experiences of men and evident in the conduct of such religious persons. This work intends to show here, the points of similarities and dissimilarities between the concept of theism in Christianity, Islam and Sikhism. This work exposed among others that their major point of way out is that in Christianity, there is a distinctive and central teaching concerning Jesus Christ as unique incarnations, the word of God, pre-eminently manifested in a historic person, on the ground that his moral character perfectly represents the character and purpose of the invisible holy God. While Islam, and Sikhism, have no such doctrine, or theory of incarnation.
