1 Corinthians 8:6

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 (KJV)

Then: Paul straightens out the meaning of "There is one God." It cannot mean that any respect is given to other Gods. God is the creator. God is Messiah. (Wright). Knowledge comes from this basic and cannot be confused with imaginary descriptions of any other god.

Now: God, Father, Son, and Spirit, endures the same, yesterday, today and tomorrow. Today's believers must know this same truth.
