A Fable I remember hearing a couple times

It is said that many centuries ago the Devil called all the demons of Hell together. He asked for suggestions as to how to damn the souls of men. 

One demon gave one suggestion; another gave another; another gave another. Then a brilliant demon came forward and said, "I’ll tell you what let’s do. Let’s tell men there is a Bible; that the Bible is God’s Word. Let’s tell men that there are a real Hell and a real Heaven; that people who die without the Saviour go to Hell; and that those who believe in Christ, when they die, go to Heaven. Let’s tell men that God loves them and has provided a way whereby they can be saved. Let’s tell men they ought to be saved, but let’s tell them they don’t need to be saved now. Let’s tell them to wait awhile."

It is said that all the demons of Hell, and even Satan himself, applauded the brilliant demon and said, "That’s it! That’s what we will do! Men will fall for that! That’s the best way to damn the souls of men!"
