...all these doctrines which deny submission deny God. Hell, a literal hell, is our only hope. Take it away & we will become wholly a wasteland not a half a one. Sin is a great thing as long as it's recognized. It leads a good many people to God who wouldn't get there otherwise. But cease to recognise sin, or take it away from devil as devil & and give it to devil as psychologist, and you also take it away from God. If there is no sin in this world there is no God in heaven. No heaven. There are those who have it that way. But even among the literary now it is becoming popular to believe in God. There is a certain something shocking about it.
