What does the Bible say about the calling of preachers?

According to Scripture, particularly Mark 6:7, God's preachers are specifically called and sent by Him. This divine calling is something that God alone can do, as exemplified by Paul's own testimony in 1 Timothy 1:12, where he acknowledges that he was enabled and found faithful because the Lord counted him worthy of ministry. The understanding here is that the right person for the ministry is not determined by human choice but by God's sovereign will and grace. Recognizing this helps maintain integrity in the ministry and ensures that preachers are faithful in delivering the gospel of Christ as entrusted to them.
