As I’d already said, Tim Keller promotes the same man-centered view of Hell spoken of above and popularized by Lewis. As I said, we wrote much on it. I even provided a link to our work. But fuggedaboutit.
On the helpfulness of the doctrine of God’s decrees, setting aside what might be true at this or that time with this or that person (which I would be a fool to question in the particular at a distance), Scripture is filled to the brim with the doctrine, so it must be endlessly profitable. And from thirty-some years in pastoral ministry, I testify that it’s often those doctrines we want to hide in this or that case for this or that reason that when, by extraordinary faith, we teach and testify to that produce the greatest fruit.
Now then, about the doctrine of God’s decrees, here is Luther’s response to Erasmus who did not so much want to argue against the doctrine as to question it’s use in this world:
Where, alas! Erasmus, are your fear and reverence of God, when you roundly declare that this branch of truth, which He has revealed from heaven, is at best, useless? What! Shall the Glorious Creator be taught by you, His creature, what is fit to be preached? Is the adorable God so very defective in knowledge, as not to know, till you instruct Him, what would be useful and what pernicious? Could He not know the consequence of His revealing this doctrine, till those consequences were pointed out by you?
Who art thou, O Erasmus, that thou shouldst reply against God! Paul, discoursing of God, says, “Whom He will He hardeneth.” And again, “God willing to show His wrath . . .” and the Apostle did not write this to have it stifled among a few persons, and buried in a corner, but wrote it to the Christians at Rome; which was, in effect, bringing this doctrine upon the stage of the whole world, stamping a universal imprimatur upon it, and publishing it to believers at large throughout the world. What can sound harsher to carnal men than those words of Christ, ‘I know whom I have chosen’?
Now these and similar assertions of Christ and His Apostles, are the very positions which you, O Erasmus, brand as useless and hurtful!”
