“When Adam and Eve willingly stepped into mortality, they knew this telestial world would contain thorns and thistles and troubles of every kind. Perhaps their most challenging realization, however, was not the hardship and danger they would endure but the fact that they would now be distanced from God, separated from Him with whom they had walked and talked, who had given them face-to-face counsel. After this conscious choice, as the record of creation says, ‘they saw him not; for they were shut out from his presence’ (Moses 5:4). Amidst all else that must have troubled them, surely this must have troubled them the most.
“But God knew the challenges they would face, and He certainly knew how lonely and troubled they would sometimes feel. So He watched over His mortal family constantly, heard their prayers always, and sent prophets (and later apostles) to teach, counsel, and guide them. But in times of special need, He sent angels, divine messengers, to bless His children, reassure them that heaven was always very close and that His help was always very near. Indeed, shortly after Adam and Eve found themselves in the lone and dreary world, an angel appeared unto them, who taught them the meaning of their sacrifice and the atoning role of the promised Redeemer who was to come.”
