1 Corinthians 1:17

17 For Christ did not send me to baptize, but to preach the gospel, not in cleverness of speech, so that the cross of Christ would not be made void.

1 Corinthians 9:16

16 For if I preach the gospel, I have nothing to boast of, for I am under compulsion; for woe is me if I do not preach the gospel.

1 Corinthians 9:18

18 What then is my reward? That, when I preach the gospel, I may offer the gospel without charge, so as not to make full use of my right in the gospel.

1 Corinthians 15:1

1 Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand,

1 Corinthians 15:2

2 by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain.
