I'm sure there are many to choose from, but here are two quotes from two of my favorite men from church history, and both in the same context. They are taken from Charles Spurgeon's message "A Defense of Calvinism," where he quotes John Newton telling a story to illustrate his point about election.
Newton quotes a woman in his congregation:
Ah! sir, the Lord must have loved me before I was born, or else He would not have seen anything in me to love afterwards.
In that sermon (which I would commend to you if you haven't read it), Spurgeon continues the discussion of the doctrine of election like this:
"I am sure it is true in my case; I believe the doctrine of election, because I am quite certain that, if God had not chosen me, I should never have chosen Him; and I am sure He chose me before I was born, or else He never would have chosen me afterwards; and He must have elected me for reasons unknown to me, for I never could find any reason in myself why He should have looked upon me with special love. So I am forced to accept that great Biblical doctrine."
And to that I can only say, "Amen."
