2 Corinthians 1:19

19 For the Son of God, Jesus Christ, who was preached among you by us, even by me and Silvanus and Timotheus, was not yea and nay, but in him was yea.

2 Corinthians 4:5

5 For we preach not ourselves, but Christ Jesus the Lord; and ourselves your servants for Jesus' sake.

2 Corinthians 11:4

4 For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
