Darkness Does Not Edify and Is Not of God

Doctrine and Covenants 50:23

23 And that which doth not edify is not of God, and is darkness.

President Marion G. Romney said: 

“Anything purporting to pertain to the gospel of Jesus Christ may be put to the following four simple tests: 1) Does it purport to originate in the wisdom of men, or was it revealed from heaven? If it originated in the wisdom of men, it is not of God. . . . 2) Does the teaching bear the proper label? . . . If any teaching purporting to be from Christ comes under any label other than that of Jesus Christ, we can know it is not of God. . . . 3) . . . The teaching must not only come under the proper label, but it must also conform to the other teaching[s] of the Gospel of Jesus Christ. 4) . . . Does it come through the proper Church channel? . . . Now, . . . if we will keep these things in mind, we shall not be deceived by false teachings.”
