1 Coríntios 9

24 Do you not know that they who run a race, all run, but one only receives the prize? So run, that you may lay hold of the prize?

25 Now, every one who contends is temperate in all things: they, indeed, that they may receive a fading crown; but we, one that does not fade.

26 I, therefore, so run, as not out of view. So I fight, not as beating the air:

27 but, I mortify my body, and keep it in subjection; lest, perhaps, having proclaimed to others, I myself should not be accepted.
