Charles H. Spurgeon on Psalms 89:43

Also turned the edge of his sword. When he goes to war he is as unsuccessful as though his sword refused to cut, and gave way like a sword of lead. His weapons fail him. And hast not made him to stand in the battle. His heart fails him as well as his sword —he wavers, he falls. This has happened even to naturally brave men —a terrible dread has unmanned them. At this present the church has few swords of true Jerusalem metal; her sons are pliable, her ministers yield to pressure. We need men whose edge cannot be turned, firm for truth, keen against error, sharp towards sin, cutting their way into men's hearts. Courage and decision are more needed now than ever, for charity towards heresy is the fashionable vice, and indifference to all truth, under the name of liberal mindedness, is the crowning virtue of the age. The Lord send us men of the school of Elias, or, at least, of Luther and Knox.
