1 Corinthians 4:9

4:9 For, I think, God has exhibited us apostles last of all, as men condemned to die, because we have become a spectacle to the world, both to angels and to people.

1 Corinthians 8:4

8:4 With regard then to eating food sacrificed to idols, we know that “an idol in this world is nothing,” and that “there is no God but one.” ¹ 

[8:4]  ¹ sn “An idol in this world is nothing” and “There is no God but one.” Here and in v. 1 Paul cites certain slogans the Corinthians apparently used to justify their behavior (cf. 6:12-13; 7:1; 10:23). Paul agrees with the slogans in part, but corrects them to show how the Corinthians have misused these ideas.
