"’Touch not the evil gift, nor the unclean thing.’ What is meant by that? Satan from the first has been a great imitator; he is an experienced strategist. Never has the Lord set his hand to do a specific thing for the good of his people upon the earth, of outstanding feature, but that Satan has attempted to imitate it in some degree.
"The Lord manifested himself to Moses, and talked to the man face to face…Then came Satan, the audacious, the father of lies, and represented himself as being the son of God in the distinctive sense. Moses was able to discern and perceive.
’And it came to pass that Moses looked upon Satan and said: Who art thou? For behold, I am a son of God, in the similitude of his Only Begotten; and where is thy glory, that I should worship thee?
For behold, I could not look upon God, except his glory should come upon me, and I were strengthened before him. But I can look upon thee in the natural man. Is it not so surely?’ (Moses 1:13-14)
"Oh, that we all had such power of discernment. That is a gift of the Spirit, to which we are entitled and we will have it as we live for it. With that gift we shall be free, to a great extent, from the deception that otherwise might lead us astray.
“As the Lord gives revelations, so does Satan, each in his way. As the Lord has revelators upon the earth, so has Satan, and he is operating upon those men by his power, and they are receiving revelations, manifestations, that are just as truly of the devil as was his manifestation to Moses, to which I have referred.” (Conference Report, Apr. 1031, p. 27)
