Early in his ministry, when he was pastor of the Congregational Church at Rugeley, Campbell Morgan studied hard and preached often.
He was discovering and developing the gift of Bible exposition that later made him the prince of expositors. His preaching made him popular.
One evening, as he sat in his study, he felt God saying to him, "What are you going to be, a preacher or My messenger?"
As Morgan pondered the question, he realized that his desire to become a "great preacher" was hindering his work. For several hours Morgan sat there struggling with God's call and human ambition.
Finally he said, "Thy messenger, my Master - Thine!"
He took the precious outlines of his sermons, messages that he was proud of, and laid them in the fireplace where they burned to ashes. That was when the victory was won.
As the outlines were burning, Morgan prayed: "If Thou wilt give me Thy words to speak, I will utter them from this day forward, adding nothing to them, taking naught away. Thine whole counsel I will declare, so help me God!" (Wycliffe Handbook of Preaching & Preachers - W. Wiersby)
"Whatever I say to you in the dark, you must tell in the light. And you must announce from the housetops whatever I have whispered to you." - Jesus (Mat 10:27 CEV)
