1 Corinthians 8:4; 1 Corinthians 8:6

4 Therefore, as to the eating of food offered to idols, we know that "an idol has no real existence," and that "there is no God but one."

6 yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist.
