This, then, it is to have the heart broken; namely, to have it lamed, disabled, and taken off by sense of God’s wrath due to sin, from that course of life it formerly was conversant in; and to show that this work is no fancy, nor done but with great trouble to the soul, it is compared to the putting the bones out of joint, the breaking of the bones, the burning of the bones with fire, or as the taking the natural moisture from the bones, the vexing of the bones, &c. (Psa 23:14; Jer 20:9; Lam 1:13; Psa 6:2; Prov 17:22). All which are expressions adorned with such similitudes, as do undeniably declare that to sense and feeling a broken heart is a grievous thing. ~ The Acceptable Sacrifice by John Bunyan
