Abba Poemen

The nature of water is soft, that of stone is hard; but if a bottle is hung above the stone, allowing the water to fall drop by drop, it wears away the stone. So it is with the Word of God; it is soft and our heart is hard, but the man who hears the Word of God often, opens his heart to the fear of God.

Sadhu Sundar Singh

While sitting on the bank of a river one day, I picked up a solid round stone from the water and broke it open. It was perfectly dry in spite of the fact that it had been immersed in water for centuries. The same is true of many people in the Western world. For centuries they have been surrounded by Christianity; they live immersed in the waters of its benefits. And yet it has not penetrated their hearts; they do not love it. The fault is not in Christianity, but in men’s hearts, which have been hardened by materialism and intellectualism.

Jonathan Edwards

The first and the great work of a Christian is about his heart. Do not be content with seeming to do good in ‘outward acts’ while your heart is bad, and you are a stranger to the greater internal heart duties. See that your chief study be about your heart; that there God’s image may be planted; that there His interests be advanced; that there the world and flesh are subdued; that there the love of every sin is cast out; that there the love of holiness grows.
