“The pilgrim is steady in his progress. ‘Yea, though I walk through the valley,’ says he. He does not run in haste: he walks quietly along. We are generally in a hurry to get our trouble over.
Cries one, ‘I feel in such a horrible state of suspense that I must end it one way or another.’ But, my dear friend, faith is not in such a frightful bustle, for—’He that believeth shall not make haste.’ Faith is quick when it has to serve God, but it is patient when it has to wait for Him.
There is no flurry about the psalmist. ‘Yea, though I walk,’ says he—quietly, calmly, steadily. So David in effect declares—I shall walk through the valley of the shadow of death as quietly as I walk in my garden in the evening, or go down the street about my business.
My affliction does not ruin me for duty, I am not flurried and worried about it. May God give you, my dear brothers and sisters, this calm faith. I pray that He may give it to me, for I greatly need it.”
–Charles H. Spurgeon, “The Valley of the Shadow of Death,” The Journal of Biblical Counseling, Vol. 18, No. 3, 2000, p. 33.
