It must be by grace alone

Men need to be told that, except divine grace shall bring them out of their enmity to God, they must eternally perish; and they must be reminded of the sovereignty of God, that He is not obliged to bring them out of this state, that He would be right and just if He left them in such a condition, that they have no merit to plead before Him, and no claims upon him, but that if they are to be saved, it must be by grace, and by grace alone. CH Spurgeon “The Soul-Winner” pg 17-18
