The preacher never needs to know the individual facts about his congregation … Why? Well, because he knows that every single human being is not righteous, and it really does not matter from the standpoint of the preacher whether they have just emerged out of a gutter or whether they have come out of the best appointed drawing room in London; it does not matter whether they have come from the West End or the East End, the North Pole or the South.
What does it matter? It does not matter how they are dressed, what they look like, how respectable or disreputable … They are souls; they are people; and therefore they are not righteous and they need this gospel because it is the only thing that can save them. And when they come to see the preacher at the end, and they begin to give a catalog of their sins, the preacher who really knows his Scriptures should say, ‘stop!
I do not mind what you have done or what you have been. You are just a sinner like everybody else and you need the same Saviour’.
(Martyn Lloyd-Jones: The Righteous Judgement of God)
Jesus paid it all,
All to Him I owe;
Sin had left a crimson stain,
He washed it white as snow.
