1 Corinthians 9:24-27

New Revised Standard Version, Anglicised Catholic Edition

²⁴ Do you not know that in a race the runners all compete, but only one receives the prize? Run in such a way that you may win it. ²⁵ Athletes exercise self-control in all things; they do it to receive a perishable garland, but we an imperishable one. ²⁶ So I do not run aimlessly, nor do I box as though beating the air; ²⁷ but I punish my body and enslave it, so that after proclaiming to others I myself should not be disqualified.
