“If our eyes were open to see the spirit world around us, … we would not be so unguarded and careless and so indifferent whether we had the spirit and power of God with us or not but we would be continually watchful and prayerful to our Heavenly Father for His Holy Spirit and His holy angels to be around about us to strengthen us to overcome every evil influence.” (George Q. Cannon, Gospel Truths, 1:82)
“Let me read you what Parley P. Pratt said about this matter. ‘In all ages and dispensations God has revealed many important instructions and warnings to men by means of dreams. When the outward organs of thought and perception are released from their activity, the nerves unstrung, the whole of mortal humanity lies hushed in quiet slumbers in order to renew its strength and vigor, it is then that the spiritual organs are at liberty in a certain degree to assume their wanted functions … Their kindred spirits, their guardian angels, then hover about them with the fondest affection, the most anxious solicitude. Spirit communes with spirit, thought meets thought, soul blends with soul, in all the raptures of mutual pure and eternal love. In this situation the spiritual organs, … our spirit body has eyes to see, ears to hear, tongue to speak, and so on … the spiritual organs are susceptible of converse with Deity, or of communion with angels, and the spirits of just men made perfect. In this situation we frequently hold communion with our departed father, mother, brother, sister, son or daughter, or with the former husband or wife of our bosom whose affections for us, being rooted and grounded in the eternal elements, issuing from under the sanctuary of love’s eternal fountain, can never be lessened or diminished by death, distance of space, or length of years.’ When we begin to understand that, beyond sight, as Brigham Young said, is the spirit world right here round about us. If our spiritual eyes could be open, we could see others visiting with us, directing us. And if we will learn not to be so sophisticated that we rule out that possibility of impressions from those who are beyond sight, then we too may have a dream that may direct us as a revelation.” (Harold B. Lee, BYU Devotional, Oct. 15, 1952)
“I am convinced that one of the profound themes of the Book of Mormon, one which may not yet have been developed enough in our teaching of young people, is the role and prevalence and central participation of angels in the gospel story… . Obviously I speak here not alone of the angel Moroni but also of those more personal ministering angels who are with us and around us, empowered to help us and who do exactly that… . Perhaps more of us … could literally, or at least figuratively, behold the angels around us if we would but awaken from our stupor and hear the words God is trying to tell us… . I believe we need to speak of and believe in and bear testimony to, the ministry of angels more than we sometimes do. They constitute one of God’s great methods of witnessing through the veil, and no document in all this world teaches that principle so clearly and so powerfully as does the Book of Mormon.” (Jeffrey R. Holland, CES Symposium, BYU, Aug. 9, 1994, pp. 16-17, 19)
“We forget that God and angels are looking upon us; we forget that the spirits of just men made perfect and our ancient fathers … are gazing upon us, and that our acts are open to the inspection of all the authorized agencies of the invisible world. And, forgetting these things sometimes, we act the part of fools, and the Spirit of God is grieved; it withdraws from us, and we are then left to grope our way in the dark.” (John Taylor, The Gospel Kingdom, p. 179)
“[A missionary testimony meeting while David O. McKay was serving in Scotland in 1899] During the progress of the meeting, an elder on his own initiative arose and said, ‘Brethren, there are angels in this room.’ … President James L. McMurrin arose and confirmed that statement by pointing to one brother sitting just in front of me saying, ‘Yes, brethren, there are angels in this room, and one of them is the guardian angel of that young man sitting there.’ And he designated one who today is a patriarch of the Church. Pointing to another elder, he said, ‘And one is the guardian angel of that young man there,’ And singled out one whom I had known from childhood… . He turned to me and … said: ‘Let me say to you Brother David, … if you will keep the faith, you will yet sit in the leading councils of the Church.’”
(David O. McKay, Cherished Experiences from the writings of President David O. McKay, Middlemiss, pp. 13-14)
“The spirits of the just are … blessed in their departure to the world of spirits… . They are not far from us, and know and understand our thoughts, feelings, and motions, and are often pained therewith.” (Teachings of the Prophet Joseph Smith, p. 326)
“Every person who desires and strives to be a Saint is closely watched by fallen spirits that came here when Lucifer fell, and by the spirits of wicked persons who have been here in tabernacles and departed from them… . Those spirits are never idle, they are watching every person who wishes to do right and are continually prompting them to do wrong.” (Brigham Young, Journal of Discourses 7:239)
“There is a vast number of fallen spirits, cast out with him here on the earth. They do not die and disappear; they have not bodies only as they enter the tabernacles of men. They … are not to be seen with the sight of the eye. But there are many evil spirits amongst us, and they labor to overthrow the Church and kingdom of God. There never was a prophet in any age of the world but what the devil was continually at his elbow.” (Wilford Woodruff, Journal of Discourses 13:163)
“If you live up to your privileges, the angels cannot be restrained from being your associates.” (Teachings of the Prophet Joseph Smith, pp. 226-227)
