We know the doctrine of preaching is true because Scripture identifies preachers as sent from God to proclaim His word.
In John 1:6, it is established that the preaching ministry is divine in origin; preachers are 'sent from God.' This declaration affirms that God equips certain individuals to preach His truth and encourages believers to recognize those whom God calls. Furthermore, the calling is confirmed through the response of the congregation—if they believe and respond to the message. Thus, sound doctrine in preaching can be known by its alignment with Scripture, the proclamation of Christ, and the positive engagement of the audience in faith.
