“For behold, my brethren, it is given unto you to judge, that ye may know good from evil; and the way to judge is as plain, that ye may know with a perfect knowledge, as the daylight is from the dark night.
For behold, the Spirit of Christ is given to every man, that he may know good from evil; wherefore, I show unto you the way to judge; for every thing which inviteth to do good, and to persuade to believe in Christ, is sent forth by the power and gift of Christ; wherefore ye may know with a perfect knowledge it is of God.
But whatsoever thing persuadeth men to do evil, and believe not in Christ, and deny him, and serve not God, then ye may know with a perfect knowledge it is of the devil; for after this manner doth the devil work, for he persuadeth no man to do good, no, not one; neither do his angels; neither do they who subject themselves unto him.
And now, my brethren, seeing that ye know the light by which ye may judge, which light is the light of Christ, see that ye do not judge wrongfully; for with that same judgment which ye judge ye shall also be judged.”
And after that he came men also were saved by faith in his name; and by faith, they become the sons of God. And as surely as Christ liveth he spake these words unto our fathers, saying: Whatsoever thing ye shall ask the Father in my name, which is good, in faith believing that ye shall receive, behold, it shall be done unto you.” – Moroni 7:15-18, 26
We have all been given the Light of Christ. This light works with our own spirits – or consciences. This Spirit can help us to judge things – whether they are good or evil.
Being able to judge is so important. Of course, we don’t want to judge unrighteously, but that doesn’t mean we should completely refrain from making judgments of any kind. There is wisdom in being judicious.
These scriptures teach the following:
Good → persuades us to believe in Christ → of God
Evil → persuades us not to believe in Christ → of the Devil
Finally, we are taught that when we ask God for something good, then we will receive it. We can encourage others to test the Book of Mormon to see if it is good. And if we want a testimony, He will help us.
