You notice that I am always preaching that Doctrine of Substitution. I cannot help it, because it is the only Truth of God that brought me comfort. I should never have gotten out of the Dungeon of Despair if it had not been for that grand Truth of Substitution! I hope that no young lady is going to ask me to write in her album this week. That request is made to me, I do not know how many days in the week, and I always write this verse in all the albums—
‘Ever since by faith I saw the stream
Your flowing wounds supply,
Redeeming love has been my theme,
And shall be till I die.’

– Charles Spurgeon, 1893, Sermon #2309
