A quote from Charles Spurgeon on the doctrine of election:
Two races have revolted against God—the one angelic, the other human. When a part of this angelic race revolted against the Most High, justice speedily overtook them. They were swept from their starry seats in Heaven and henceforth they have been reserved in darkness unto the great day of the wrath of God! No mercy was ever presented to them; no sacrifice ever offered for them. They were without hope and mercy, forever consigned to the pit of eternal torment! The human race, far inferior in order of intelligence, sinned as atrociously—at any rate, if the sins of manhood that we have heard of were put together and rightly weighed, I can scarcely understand how even the sins of devils could be much blacker than the sins of mankind! However, the God who in His Infinite Justice passed over angels and allowed them forever to expiate their offenses in the fires of Hell, was pleased to look down on man. Here was election on a grand scale! The election of manhood and the reprobation of fallen angelhood! What was the reason for it? The reason was in God’s mind—an inscrutable reason which we do not know and even which if we did know, we probably could not understand. Had you and~Charles Spurgeon (Free Grace 233.66)
I been put given the choice of which would have been spared, I think it probable we would have chosen that fallen angels should have been saved. Are they not the brightest? Have they not the greatest mental strength? If they had been redeemed, would it not have glorified God more, as we judge, than the salvation of worms like ourselves? Those bright beings—Lucifer, son of the morning and those stars that walked in his train—if they had been washed in His redeeming blood; if they had been saved by Sovereign Mercy, what a song would they have lifted up to the Most High and everlasting God! But God, who does as He wills with His own and gives no account of His matters; He who deals with His creatures as the potter deals with his clay—took not upon Him the nature of angels, but took upon Him the seed of Abraham and chose men to be the vessels of His mercy! This fact we know, but what is its reason? Certainly not in man! “Not for your sakes do I this. O house of Israel, be ashamed and be confounded for your own ways.”
Here, very few men object. We notice that if we talk about the election of men and the non-election of fallen angels, there is not a cavil for a moment! Every man approves of Calvinism till he feels that he is the loser by it. But when it begins to touch his own bones and his own flesh, then he kicks against it. Come, then, we must go further! The only reason why one man is saved and not another lies not, in any sense, in the man saved, but in God’s bosom!
