A.W. Tozer emphasizes the profound significance of preaching as the means through which God manifests His Word to humanity. He reflects on the divine condescension that allows imperfect preachers to convey a perfect message, highlighting the weighty responsibility that both preachers and hearers bear in this sacred exchange. Tozer illustrates the historical impact of preaching, from Noah to modern-day ministers, and stresses that the effectiveness of preaching lies not in the medium but in the divine authority behind it. He warns against the dangers of laziness and cowardice in ministry, urging preachers to recognize the eternal implications of their message. Ultimately, he calls for a deep awareness of the responsibility of both the messenger and the listener in the pursuit of spiritual truth.
