In his book Preachers and Preaching, Martyn Lloyd-Jones noted, "I shall never cease to be grateful to Richard Sibbes, who was balm to my soul at a period in my life when I was overworked and badly overtired, and therefore subject in an unusual manner to the onslaughts of the devil.... I found at that time that Richard Sibbes... was an unfailing remedy. His books The Bruised Reed and The Soul's Conflict quietened, soothed, comforted, encouraged, and healed me."

In this book, Sibbes reflects on Psalm 42:11 - "Why art thou cast down, O my soul? and why art thou disquieted within me? hope thou in God; for I shall yet praise him, who is the health of my countenance, and my God."

There be two sorts of people always in the visible Church; one that Satan keeps under with false peace, whose life is nothing but a diversion to present contentments, and a running away from God and their own hearts, which they know can speak no good unto them, these speak peace to themselves, but God speaks none. Such have nothing to do with this scripture; the way for these men to enjoy comfort, is to be soundly troubled. True peace arises from knowing the worst first, and then our freedom from it. It is a miserable peace that ariseth from ignorance of evil. The angel troubled the waters, John v., and then cured those that stepped in. It is Christ's manner to trouble our souls first, and then to come with healing in his wings.

But there is another sort of people, who being drawn out of Satan's kingdom and within the covenant of grace, whom Satan labours to unsettle and disquiet: being the god of the world, he is vexed to see men in the world, walk above the world. Since he cannot hinder their estate, he will trouble their peace, and damp their spirits, and cut asunder the sinews of all their endeavours.
