So, is there a "hell?" (D&C 19: 15.) Do those who go there suffer? How difficult is the suffering? (D&C 19: 16-18.)
Would the false doctrines make them and those hearing from them feel secure, or would it stir them up to repentance?
We seem to all be asleep and incapable of noticing this terrible warning. Why cannot we all awake and arise and put on the beautiful garments, going forth to meet with the Bridegroom? (Moroni 10: 31; D&C 133: 10.)
This Book of Mormon is alarming when we consider it a warning for us. Not at all the docile and superficial text we can turn it into when studying 8 chapters in a single 50 minute Gospel Doctrine class-- reduced by the time taken for announcement, opening and closing prayers, and witty banter exchanged among affable Saints as part of our renewal of weekly fellowship. Those things are good, of course, but the book commands deeper attention.
Take the Book of Mormon seriously. Apply it to yourself. Not as a means to judge others, but as a means to test your own life. It is one thing to evaluate our circumstances, which the book compels us to do, but we needn't go further than to realize our terrible plight. From that moment the warning should work inside ourselves to help us improve within, see more clearly our day, think more correctly about what is going on, and act more consistent with the Lord's purposes.
