You have treated lightly the things you have received

And your minds in times past have been darkened because of unbelief, and because you have treated lightly the things you have received, which vanity and unbelief have brought the whole church under condemnation. And this condemnation rests upon the children of Zion, even all, and they shall remain under this condemnation until they repent and remember the new covenant, even the Book of Mormon, and the former commandments which I have given them, not only to say, but to do, according to that which I have written, that they may bring forth fruit meet for their Father’s Kingdom. Otherwise, there remains a scourge and a judgment to be poured out upon the children of Zion, for shall the children of the Kingdom pollute my holy land? Verily, verily I say unto you, Nay.

T&C 82:20
