Martyn Lloyd-Jones description of preaching in his lectures published under the title Preaching and Preachers, delivered as lectures at Westminster Theological Seminary, Philadelphia, PA, in 1969:
What is preaching? Logic on fire! Eloquent reason! Are these contradictions? Of course they are not. Reason concerning this Truth ought to be mightily eloquent, as you see it in the case of the Apostle Paul and others. It is theology on fire. And a theology that does not take fire, I maintain, is a defective theology; or at least the man’s understanding of it is defective. Preaching is theology coming through a man who is on fire. What is the chief end of preaching? I think it is this: To give men and women a sense of God and His presence . As I have said already, during this past year I have been ill, and so have had the opportunity, and the privilege, of listening to others, instead of preaching myself. As I have listened in physical weakness this is the thing I looked for and have longed for and have desired. I can forgive a man for a bad sermon, I can forgive the preacher almost anything if he gives me a sense of God, if he gives me something for my soul, if he gives me a sense that, though he is inadequate in himself, he is handling something which is very great and very glorious, if he gives me some dim glimpse of the majesty and glory of God, the love of Christ my Savior, and the magnificence of the gospel. If he does that I am his debtor, and I am profoundly grateful to him. Preaching is the most amazing, the most thrilling activity that one can ever be engaged in, because of all that it holds out for all of us in the present, and because of the glorious endless possibilities in an eternal future.
