It is as much as if he had said, Lord! How should I believe on him, of whom I have not heard? (So the disciples answered Paul, asking them whether they had received the Holy Ghost, Wehave not so much as heard whether there be any Holy Ghost, Act_19:2). But, saith he, Lord, I am ready to believe on him, may I but know who he is. Our Lord had prepared this poor man’s heart for the receiving of him; there wanted now nothing but the due revelation of the Messiah unto him. This our Saviour giveth him.
