Hinduism acknowledge multitudes of gods and goddesses.  Buddhism says there is no deity.  New Age Spirituality followers believe they are God.  Islam believes in a powerful but unknowable God.  It is only Christianity that reveals a God who desires to have a personal relationship.  It is only Christianity that reveals a God that comes to earth in order to make it possible for us sinners to have a right relationship with God the Father.  It is only Christianity that reveals a God who showers on us grace upon grace.
