God is One God

Hear, O Israel: The LORD our God is one LORD: (Deuteronomy 6:4)

But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him. (1 Corinthians 8:6)

There is none holy as the LORD: for there is none beside thee: neither is there any rock like our God. (1 Samuel 2:2)

I am the LORD, and there is none else, there is no God beside me: I girded thee, though thou hast not known me (Isaiah 45:5)
