How do we know that preachers are sent by God?

The affirmation that preachers are sent by God is rooted in scripture, particularly in Romans 10:14-15. It states that beautiful are the feet of those who preach the good news. Unlike human appointments that might rely on experience or ability, God's calling is divine and sovereign. A true preacher recognizes that he is a servant of Christ, called not by men but chosen by God for the purpose of declaring His gospel. This operating under divine authority sets faithful preachers apart in their mission.
