If one understands the things of the Lord, one can discern whether or not something has come from God. The Book of Mormon gives us a key to make such discernments, every thing which inviteth and enticeth to do good, and to love God, and to serve him, is inspired of God (Moroni 7:13). Nephi concludes his record along these same lines—if the people of the latter days really believe in Christ, they will recognize the writings of Nephi as the words of Christ, if ye shall believe in Christ ye will believe in these words, for they are the words of Christ…And if they are not the words of Christ, judge ye—for Christ will show unto you, with power and great glory, that they are his words at the last day (2 Nephi 33:10-1).
