Plenty of people ignore the words of prophets and apostles. They don't talk nicely. They say difficult things in the name of Christ, often in opposition to how many proclaim that Jesus love them.
27 And I exhort you to remember these things; for the time speedily cometh that ye shall know that I lie not, for ye shall see me at the bar of God; and the Lord God will say unto you: Did I not declare my words unto you, which were written by this man, like as one crying from the dead, yea, even as one speaking out of the dust?
I like the picture painted here. Moroni is at your turn at judgment. If you choose to act like you didn't know what the prophet said or warned about, God himself will indict you. As you think of all the prophets that have issued warnings, that might make the idea of judgment less than appealing to many.
Don't be that person! Listen and heed to the prophets.
30 And again I would exhort you that ye would come unto Christ, and lay hold upon every good gift, and touch not the evil gift, nor the unclean thing.
