There is so much quotable wisdom in Preaching and Preachers
by D. Martyn Lloyd-Jones that it’s hard to know where to begin. This, though, is one of my favorites:
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 the sense that, though he is inadequate himself, he is handling something which is very great and very glorious, if he gives me some dim glimpse of the majesty and the glory of God, the love of Christ my Saviour, and the magnificence of the Gospel. If he does that I am his debtor, and I am profoundly grateful to him.
