Guru Nanak regularly used the term Akal Purakh, meaning the Eternal One, to describe God. God is therefore viewed as timeless and immortal. Sikhs regularly use the word Waheguru to describe God.
Although most Sikhs believe there is one god, many believe Sikhism is not the only way to have a relationship with God. People of any religion or no religion can have a relationship with God, who created each of us and gave us the ability to know the difference between right and wrong.
