哥林多前書 I Corinthians 9:26-27
所以，我奔跑不像無定向的；我鬥拳不像打空氣的。我是攻克己身，叫身服我，恐怕我傳福音給別人，自己反被棄絕了。
Therefore I do not run like someone running aimlessly; I do not fight like a boxer beating the air. No, I strike a blow to my body and make it my slave so that after I have preached to others, I myself will not be disqualified for the prize.
