The Devil is a Son of God:
The Devil Desired Power:
The Devil Rebelled:
"Satan rebelled against me, and sought to destroy the agency of man, which I, the Lord God, had given him, and also, that I should give unto him mine own power" (Moses 4:3).Lucifer rebelled against God and began a war in Heaven. One third of the hosts of heaven followed Lucifer,3 but all were cast out of heaven to forever be denied the blessing of a physical body and to never return to the presence of God. Upon being cast out, Lucifer became known as Satan or the devil:
"And he became Satan, yea, even the devil, the father of all lies, to deceive and to blind men, and to lead them captive at his will, even as many as would not hearken unto my voice (Moses 4:4)."Satan's rebellion led to his fall from grace, and now he and his followers are sons of perdition.
The Devil is Real:
The devil and his angels seek to destroy us by tempting and deceiving us. They try to lead us away from God and Christ. Indeed, one of the devil's greatest deceptions is to persuade us that "there is no devil."
"And behold, others he flattereth away, and telleth them there is no hell; and he saith unto them: I am no devil, for there is none—and thus he whispereth in their ears, until he grasps them with his awful chains, from whence there is no deliverance" (2 Nephi 28:22).
Scriptures State that the Devil is Real:
"For I say unto you that whatsoever is good cometh from God, and whatsoever is evil cometh from the devil" (Alma 5:40).From the New Testament we know that Christ cast out devils (Satan's followers) and was tempted by Satan himself. Not only do the scriptures and prophets testify of the reality of the devil but you can know for yourself, through the power of the Holy Ghost, that the devil is real.
We Must Not Be Decieved:
"We Latter-day Saints need not be, and we must not be, deceived by the sophistries of men concerning the reality of Satan. There is a personal devil, and we had better believe it. He and a countless host of followers, seen and unseen, are exercising a controlling influence upon men and their affairs in our world today."5
