Charles Spurgeon
If you long to save men's souls, you must tell them a great deal of disagreeable truth.

The flesh and blood of Christ are not less truly given to the unworthy than to the elect believers of God; and yet it is true, that just as the rain falling on the hard rock runs away because it cannot penetrate, so the wicked by their hardness repel the grace of God, and prevent it from reaching them.
John Calvin
