“Wax receives an impression from a seal, but not the stern, unyielding stone; if you have hot running wax you may make what mark you please upon it, but when you have the cold, cold stone, though you bear never so hard upon the stamp, there is no impression, the surface shows no trace of your labor. So is man’s heart by nature. I know some who say it is not so, they do not like to hear human nature slandered, so they say. Well, friend, if thou hast not this hard heart, why is it thou art not saved?
I remember an anecdote of Dr. Gill which hits this nail on the head. It is said that a man came to him in the vestry of his chapel and said,
“Dr. Gill, you have been preaching the doctrine of human inability, I don’t believe you. I believe that man can repent and can believe, and is not without spiritual power.”
“Well,” said the doctor, have you repented and believed?”
“No,” said the other.
“Very well, then,” said he, “you deserve double damnation.”
And so I say to the man who boasts that he has not such a hard heart as this-have you laid hold of Christ? have you come to him? if you have not, then out of your own heart be you condemned, for you deserve double destruction from the presence of God, for having resisted the influences of God’s Spirit and rejected his grace. I need not say more about the hardness of the human heart, as that will come up incidentally by-and-bye, when we are speaking of the heart of flesh” – Spurgeon
