Charles H. Spurgeon on Psalms 130:4

But there is forgiveness with thee, that thou mayest be feared. Even Saul himself will lift up his voice and weep when he seeth a clear testimony of the love and undeserved kindness of David. Hast thou never beheld a condemned prisoner dissolved in tears upon the unexpected and unmerited receipt of a pardon, who all the time before was as hard as a flint? The hammer of the law may break the icy heart of man with terrors and horrors, and yet it may remain ice still, unchanged; but when the fire of love kindly thaws its ice, it is changed and dissolved into water —it is no longer ice, but of another nature. —George Swinnock.
