Quote context

[...]

- Though I should have been happy to have numbered him among my own flock, George Fotheringay was a nonconformist.

- He was a regular chapel-goer, and the following Sunday evening found him in chapel as usual.

- It was there that he heard a sermon which made a profound impression on him. It was delivered by Mr. Maydig, the lay preacher.

- What shall it profit a man if he gain the whole world and lose his own soul?

- It's not lawful for us to take upon ourselves those acts which are not in man's normal power to effect.

- And who so makes his bargain with Mephistopheles, that good may accrue from it to himself, shall find in the fullness of time that the price must be paid in full.

- Therefore I say unto you, my brethren...

- The tenor of that sermon threw an entirely new light on the gifts which Fotheringay had developed, and he decided to consult Mr. Maydig immediately after the service.

- It was in Mr. Maydig's study that he finally unburdened himself.

- I can only say that I didn't make such a pact with anybody.
