The ancient American Prophet Nephi prophesied about the worldly philosophies that would be taught in the latter days. Basically saying that in the last days many people will say that it is all right to commit a little sin. Here are his words:
Yea, and there shall be many which shall say: Eat, drink, and be merry, for tomorrow we die; and it shall be well with us.
And there shall also be many which shall say: Eat, drink, and be merry; nevertheless, fear God—he will justify in committing a little sin; yea, lie a little, take the advantage of one because of his words, dig a pit for thy neighbor; there is no harm in this; and do all these things, for tomorrow we die; and if it so be that we are guilty, God will beat us with a few stripes, and at last we shall be saved in the kingdom of God.
Yea, and there shall be many which shall teach after this manner, false and vain and foolish doctrines, and shall be puffed up in their hearts, and shall seek deep to hide their counsels from the Lord; and their works shall be in the dark.
Beginning today, we should stop committing some so-called little sins.
