Take heed that ye despise not one of these little ones; for I say unto you, That in heaven their angels do always behold the face of my Father which is in heaven. Matthew 18:10. AG 364.1
Not until the providences of God are seen in the light of eternity shall we understand what we owe to the care and interposition of His angels. Celestial beings have taken an active part in the affairs of men. They have appeared in garments that shone as the lightning; they have come as men, in the garb of wayfarers. They have accepted the hospitalities of human homes; they have acted as guides to benighted travelers.... AG 364.2
Though the rulers of this world know it not, yet often in their councils angels have been spokesmen. Human eyes have looked upon them. Human ears have listened to their appeals. In the council-hall and the court of justice, heavenly messengers have pleaded the cause of the persecuted and oppressed. They have defeated purposes and arrested evils that would have brought wrong and suffering to God's children. To the students in the heavenly school, all this will be unfolded. AG 364.3
Every redeemed one will understand the ministry of angels in his own life. The angel who was his guardian from his earliest moment; the angel who watched his steps, and covered his head in the day of peril; the angel who was with him in the valley of the shadow of death, who marked his resting-place, who was the first to greet him in the resurrection morning—what will it be to hold converse with him, and to learn the history of divine interposition in the individual life, of heavenly cooperation in every work for humanity! 42Education, 304, 305.

With the Word of God in his hands, every human being ... may have such companionship as he shall choose.... He may dwell in this world in the atmosphere of heaven, ... drawing nearer and nearer the threshold of the eternal world, until the portals shall open, and he shall enter there. He will find himself no stranger. The voices that will greet him are the voices of the holy ones, who, unseen, were on earth his companions—voices that here he learned to distinguish and to love. He who through the Word of God has lived in fellowship with heaven, will find himself at home in heaven's companionship.43Education, 127. AG 364.5
