'Preach' in the Bible

Now when I arrived at Troas to preach the good news of Christ, even though a door [of opportunity] opened for me in the Lord,

For we do not preach ourselves, but Jesus Christ as Lord, and ourselves [merely] as your bond-servants for Jesus’ sake.

so that we may preach the gospel even in the lands beyond you, but not to boast in work already accomplished in another one’s field of activity.
