I discovered Martin Tupper’s Proverbial Philosophy while watching a movie about the life of the influential English Baptist preacher, Charles Spurgeon.
In the movie, Mr. Spurgeon’s future wife reads from a passage in the book:
If thou art to have a wife of thy youth, she is now living on the Earth;
Therefore think of her, and pray for her; yea, though thou has not seen her.
“Do you pray for him who is to be your husband?” he asked her.
Martin Farquhar Tupper (July 1810 – November 1889) was an English writer, and poet, and the author of Proverbial Philosophy. You can read the whole book for free on Project Gutenburg
