Thielicke on Spurgeon on Pastors

We preach "Do not be anxious!" --and at the same time worry ourselves to death about whether everybody will hear this. We say, "God reigns"--and still we run about madly keeping the ecclesiastical machinery going. We proclaim man's passive righteousness (the righteousness that comes from God)--and still we behave like activists.  We preach eternity; but when Jesus asks us, "Did you have enough of everything?" We will have to reply, "Oh, no; we didn't have enough time." This is why we preach peace and radiate restlessness.  This is why we give stones instead of bread, and men do not believe us.
