3 nephi 6:15-18
15 Now the cause of this iniquity of the people was this—Satan had great power, unto the stirring up of the people to do all manner of iniquity, and to the puffing them up with pride, tempting them to seek for power, and authority, and riches, and the vain things of the world.
16 And thus Satan did lead away the hearts of the people to do all manner of iniquity; therefore they had enjoyed peace but a few years.
17 And thus, in the commencement of the thirtieth year—the people having been delivered up for the space of a long time to be carried about by the temptations of the devil whithersoever he desired to carry them, and to do whatsoever iniquity he desired they should—and thus in the commencement of this, the thirtieth year, they were in a state of awful wickedness.
18 Now they did not sin ignorantly, for they knew the will of God concerning them, for it had been taught unto them; therefore they did wilfully rebel against God.
James 4
There is one lawgiver, who is able to save and to destroy: who art thou that judgest another?
13Go to now, ye that say, To day or to morrow we will go into such a city, and continue there a year, and buy and sell, and get gain:
14Whereas ye know not what shall be on the morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away.
15For that ye ought to say, If the Lord will, we shall live, and do this, or that.
16But now ye rejoice in your boastings: all such rejoicing is evil.
17Therefore to him that knoweth to do good, and doeth it not, to him it is sin.
