The Psalms, speaking as if God were a surgeon who binds and bandages wounds, say about Him, among other things, that He heals those who are afflicted and have a broken heart (Psalm 103:3, 147:3). We need that teaching very much. As soon as we are grieved and displeased, we feel like our faith is beaten down and we cannot show its effectiveness. Consequently, it is impossible to glorify God and find rest in Him and His goodness if we do not have the assurance that He and He alone can lessen all our sadness.
– John Calvin, Sermon 61, Sermons on Genesis
