Bunyan's Picture of a True Gospel Pastor

From John Bunyan's Pilgrim's Progress (Christian has just arrived at the house of the Interpreter):

So [the Interpreter] commanded His servant to light the candle and then asked Christian to follow Him to a private room that, when the manservant opened the door, revealed a picture of a very grave person hanging on the wall. This is what the man in the picture looked like: he had eyes lifted up to Heaven, the best of books in his hand, the law of truth written upon his lips, the world behind his back. He stood as if pleading with men, and a crown of gold hung over his head.

Then said Christian, "What does this mean?"

"The man in this picture represents one of a thousand: he can conceive children, travail in birth with children, and nurse them himself when they are born. You see him with his eyes lifted up to Heaven, the best of books in his hand and the law of truth written on his lips. All this is to show you that his work is to know and unfold dark things to sinners. You see him pleading with men, the world cast behind him, and a crown hanging over his head to show you that by rejecting and despising the things of this present world for the love that he has for his Master's service, he is sure to have glory as his reward in the world to come. I have shown you this picture first because the man whom it represents is the only man authorized by the Lord of the place where you are going to be your guide in all the difficult places you will encounter on the way. So pay attention to what I have shown you, and keep this picture foremost in your mind, so that if you meet with someone who doesn't resemble this picture's likeness but who pretends to lead you in the right way, you will not follow him down to destruction."
