1 Corinthians 9:24

9:24 Do you not know that all the runners in a stadium compete, but only one receives the prize? So run to win.

[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.
