Oh, that we could all realize the nearness of heaven to earth! When the earthborn children know it not, they have the angels of light as their companions; for the heavenly messengers are sent forth to minister to those who shall be heirs of salvation. A silent witness guards every soul that lives, seeking to win and draw him to Christ. The angels never leave the tempted one a prey to the enemy who would destroy the souls of men if permitted to do so. As long as there is hope, until they resist the Holy Spirit to their eternal ruin, men are guarded by heavenly intelligences.
Oh, that all could behold our precious Saviour as He is, a Saviour. Let His hand draw aside the veil which conceals His glory from our eyes. It shows Him in His high and holy place. What do we see? Our Saviour, not in a position of silence and inactivity. He is surrounded with heavenly intelligences, cherubim, and seraphim, ten thousand times ten thousand of angels. All these heavenly beings have one object above all others, in which they are intensely interested—His church in a world of corruption.... They are working for Christ under His commission, to save to the uttermost all who look to Him and believe in Him.
Heavenly angels are commissioned to watch the sheep of Christ’s pasture. When Satan with his deceptive snares would deceive if possible the very elect, these angels set in operation influences that will save the tempted souls if they will take heed to the Word of the Lord, realize their danger, and say, “No, I will not enter into that scheme of Satan. I have an Elder Brother on the throne in heaven, who has shown that He has a tender interest in me, and I will not grieve His heart of love.”
Living amid these opposing forces, we may through the exercise of faith and prayer, call to our side a retinue of heavenly angels, who will guard us from every corrupting influence. OHC 23
There we shall know even as also we are known. There the loves and sympathies that God has planted in the soul will find truest and sweetest exercise. The pure communion with holy beings, the harmonious social life with the blessed angels and with the faithful ones of all ages, the sacred fellowship that binds together “the whole family in heaven and earth” all are among the experiences of the hereafter.—Education, 306 quoted in The Adventist Home, 548, 549.

"For he shall give his angels charge over thee, to keep thee in all thy ways." Psalm 91:11 (King James Version)
