God is called many different names in the Bible, mainly because of the different dimensions of His personality, but God is One (Deuteronomy 6:4). God is super-dimensional and eternally self-existent (John 8:54-59). God is omniscient, omnipresent and omnipotent; He is the Creator of the heavens and the earth (Genesis 1 & 2). While God is indeed one, He exists in three distinct persons, God the Father, God the Son (Jesus) and God the Holy Spirit; each having the same nature and attributes, but each with distinct office and activities.
(Matthew 28:19; 2 Corinthians 13:14)
