This is from Bryan Chapell's Cross Centered Preaching. In this chapter, he has been talking about various processes of explanation. As a teacher, I found this very convicting:
In one of the key debates during the formulation of the Westminster Confession of Faith, one scholar spoke with great skill and persuasiveness for a position that would have mired the church in political debates for many years. As the man spoke, George Gillespie prepared a rebuttal in the same room. As they watched him write furiously on a tablet, all in the asembly knew the pressure on the young man to organize a response while the scholar delivered one telling argument after another. Yet when Gillespie rose, his words were filled with such power and scriptural persuasion that the haste of his preparation was not discernible. Gillespie's message so impressed those assembled as the wisdom of God that the opposing scholar conceded that a lifetime of study had jus been undone by the younger man's presentation. When the matter was decided, the friends of Gillespie snatched from his desk the tablet on which he had so hastily collected his thoughts. They expected to find a brilliant summary of the words so masterfully just delivered. Instead, they found only one phrase written over and over again: Da Luem, Domine (Give light, O Lord).
Over and over Gillespie had prayed for more light from God. Instead of the genius of his own thought, this valiant Reformer wanted more of the mind of God.
In this chapter, Chapell reiterates the need for plain, accurate terms of explanation. Looking for elaborate or novel ways to explain the text may not be as effective as simply and clearly teaching what the text says and what it means. I do think that there is a place for teaching students theological terms, but this is where knowing our students becomes important. Some students will be keen and care about such things. Others may be quite content with the simplest explanation. As a teacher, my goal is to know my students and to be like Mr. Gillespie and cry out "Give light, O God!"
