1 Corinthians 8:4
“As concerning therefore the eating of those things that are offered in sacrifice unto idols, we know that an idol is nothing in the world, and that there is none other God but one.”
And if any man think that he knoweth any thing, he knoweth nothing yet as he ought to know.
But if any man love God, the same is known of him.
As concerning therefore the eating of those things that are offered in sacrifice unto idols, we know that an idol is nothing in the world, and that there is none other God but one.
For though there be that are called gods, whether in heaven or in earth, (as there be gods many, and lords many,)
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.
