A: Guru Granth Sahib, the Sikh Holy Scripture describes the characteristics of God. Through the 1430 pages the Guru Granth Sahib explains about God, praises God, and informs on what essentially makes God.
The opening of the Scripture is a description of God: ‘God is one. He is the supreme truth. He, the Creator, is beyond fear and beyond hate. He is immortal. He is neither born and nor does He die. By Guru’s grace shall He be met. In the beginning He was the truth. Throughout the ages He has been the truth. He is the truth here and now and He shall be the truth forever’ (Guru Granth Sahib, 1).
The most important aspect of being a Sikh, is to understand that, there is one endless God. He is indescribable, inestimable, indubitable, infallible, intangible, imperishable, immutable, immortal, immaculate, immanent, unconquerable, unique, formless, fearless, deathless, timeless, ageless, compassionate, omnipresent and creator of all.

God loves everyone. Sikhs believe there is no one superior to God. Furthermore, Sikhs believe that God created all beings, all animals, birds, all creatures, including humans. When the First Great Guru, the founder of Sikh faith, Guru Nanak Dev gave this definition to the people who believed differently in God, they were surprised and they asked him, who told you this and how God came in existence? The Great Guru said, “God Himself told me that He is self-created.” They asked him, “how does God look?" and the Great Guru preached that God is formless. God is beyond gender and form. God has no body. Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/showthread.php?t=16
The main difference between Sikhism and some of the world’s other religions is that there are people who worship Jesus and believe Jesus is God, some people worship Buddha and believe Buddha is God. The Sikh Gurus themselves said that they are not to be worshipped. They expressed very clearly not to worship anyone except God.
