24 Do you not know that those who run in a race all run , but only one receives the prize ? Run in such a way that you may win . 25 Everyone who competes in the games exercises self-control in all things . They then do it to receive a perishable wreath , but we an imperishable . 26 Therefore I run in such a way , as not without aim ; I box in such a way , as not beating the air ; 27 but I discipline my body and make it my slave , so that, after I have preached to others , I myself will not be disqualified .
