Thankful for this very good reminder, from an excellent book:
Rightly dividing the Word of truth, then, is the central mark of a truly successful preacher. In the end, when he stands before the Chief Shepherd, only one factor about his ministry will ultimately matter: Was he faithful? He may have been a dynamic orator, a master storyteller, and a winsome communicator. His church might have been large and his ministry well known. But if his own faithfulness is absent, all of those externals are merely wood, hay, and straw (cf. 1 Cor. 3:10–15).
