1 Corinthians 9:25-27

LITV(i) 25 But everyone striving controls himself in all things. Then those truly that they may receive a corruptible crown, but we an incorruptible. 26 So I run accordingly, as not uncertainly; so I fight, as not beating air; 27 but I buffet my body and lead it captive, lest proclaiming to others I myself might be rejected.
