1 Corinthians 9:25; 1 Corinthians 10:11; 1 Corinthians 10:28; 1 Corinthians 15:11

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.
11 Now all these things happened unto them for examples: and they are written for our admonition, upon whom the ends of the world are come .
28 But if any man say unto you, This is offered in sacrifice unto idols, eat not for his sake that shewed it , and for conscience sake: for the earth is the Lord's, and the fulness thereof:
11 Therefore whether it were I or they, so we preach , and so ye believed .
