“If our hearts were a slab of concrete, and we wanted to keep them that way, our desire to have them caressed with a feather duster would exhibit no love of tenderness, but rather the contrary. The one who really wanted a tender heart would be calling for the jackhammer. Hard words, hard teaching, are the jackhammer of God . . . When Christians call for smooth words, easy words, the result is hard people. When we submit to hard words, we become the tenderhearted of God.”
