Tim Keller, pastor at Redeemer Presbyterian Church in NYC offers some important words on the necessity of preaching the tough doctrines of the Christian faith, notably the doctrine of judgment and Hell. Here is a sample:
“Thus, it's tempting to avoid such topics in our preaching. But neglecting the unpleasant doctrines of the historic faith will bring about counter-intuitive consequences. There is an ecological balance to scriptural truth that must not be disturbed.
If an area is rid of its predatory or undesirable animals, the balance of that environment may be so upset that the desirable plants and animals are lost—through over breeding with a limited food supply. The nasty predator that was eliminated actually kept in balance the number of other animals and plants necessary to that particular ecosystem. In the same way, if we play down "bad" or harsh doctrines within the historic Christian faith, we will find, to our shock, that we have gutted all our pleasant and comfortable beliefs, too.
The loss of the doctrine of hell and judgment and the holiness of God does irreparable damage to our deepest comforts—our understanding of God's grace and love and of our human dignity and value to him. To preach the good news, we must preach the bad.”
