Iain Boyd has been reading this book and been blessed by it greatly. Here’s a quote from the book.
“After conversion we need bruising, that reeds may know themselves to be reeds and not oaks. Even reeds need bruising by reason of the remainder of pride in our nature, and to let us see that we live by mercy. . . . Thus Peter was bruised when he wept bitterly. This reed, till he met with this bruise, had more wind in him than pith. ‘Though all forsake thee, I will not.’ The people of God cannot be without these examples. The heroic deeds of those great worthies do not comfort the church so much as their falls and bruises do.”
Richard Sibbes, “The Bruised Reed,” in Works (Edinburgh, 1979), I:44.
