Bunyan:
Truly, you must go to him that can make the eyes that are blind to see, even to our Lord Jesus, by prayer, saying, as the poor blind man did, 'Lord, that I might receive my sight'; and so continue begging with him, till you receive sight, even a sight of Jesus Christ, his death, blood, resurrection, ascension, intercession, and that for thee, even for thee.
Objection: But, alas, I have nothing to carry with me; how then should I go?
Answer: Have you no sins? If you have, carry them, and exchange them for his righteousness. If you do but come to him, he will give you rest.
--John Bunyan,
The Law and Grace Unfolded, in Works, 1:572
