1 Corinthians 9:24-27

Mace(i) 24 You know, that in a race, tho' all run, but one receives the prize: so run, that you may obtain. 25 every one that strives for the mastery, is extremely temperate: now, they do it to obtain a corruptible crown, but we an incorruptible one. 26 I therefore so run, not as one that is distanc'd: I fight, but not with the air. 27 but I mortify my body, and bring it into subjection: lest after having been a herald to others, I my self should be thrown out.
