C.H. Spurgeon considered Unconditional Election to be one of the greatest truths in the whole of revelation.
This is the third article in the series “C.H. Spurgeon on the Doctrines of Grace,” which discusses Spurgeon’s views on Calvinism as seen in his preaching and writing.
Spurgeon unabashedly preached on the reality of election and the sovereignty of God in saving sinners. Still, he understood that the doctrine of election can be a difficult concept for many to grasp. He began one sermon on the subject by addressing a hypothetical objection:
At the very announcement of the text some will be ready to say, “Why preach upon so profound a doctrine as election?” I answer, because it is in God’s word, and whatever is in the Word of God is to be preached. 
As we saw in the previous article, the doctrine of Total Depravity reveals how utterly incapable we are to save ourselves. Scripture affirms this truth and teaches that it is God who saves us according to His sovereign will (Ephesians 2:8-9; John 6:65).
