I can forgive a man 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 in himself, he is handling something which is very great and glorious, if he gives me some dim glimpse of the majesty and 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.

D. Martin Lloyd-Jones (1899-1981)
