In the Bible, the most common words used for a preacher are minister [diakonos – servant] (1 Timothy 4:6), preacher [kerux – herald of divine truth] (2 Timothy 1:11), and evangelist [euaggelistes – proclaimer of good news] (2 Timothy 4:5). The description of the gospel preacher is clearly shown in the texts of First and Second Timothy and Titus.
The preacher’s work can be summarized in 2 Timothy 4:1-5. Preachers are to “preach the word” “Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine”. 2 Timothy 4:2
