1 Corinthians 9:27

27 But I keep under my body, and bring it into subjection: lest that by any means*, when I have preached to others, I myself should be a castaway.

1 Corinthians 9:27 In-Context

25 And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible.
26 I therefore so run, not as uncertainly; so fight I, not as one that beateth the air:
27 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
