From the chapter by Melvin Curry:
You may grow weary and waver in your commitment to proclaim the gospel. Sources of discontent range from the indifference of brethren to doctrinal departures from the faith. I confess there were times I became discouraged and thought about quitting. But, like Jeremiah, when I said, “I will not make mention of Him, nor speak anymore in His name, . . . His word was in my heart like a burning fire shut up in my bones; I was weary of holding it back, and I could not” (Jeremiah 20:9). “If I preach the gospel,” Paul said, “I have noting to boast of, for necessity is laid upon me; yes, woe is me if I do not preach the gospel! For if I do this willingly, I have a reward; but if against my will, I have been entrusted with a stewardship” (1 Corinthians 9:16-17). Thus, I have never been able with a clear conscience to escape the stewardship of preaching. And, most likely, neither will you be able to do so.
