From the beginning down through the dispensations, God has used angels as His emissaries in conveying love and concern for His children….
Usually such beings are not seen. Sometimes they are. But seen or unseen they are always near.
In the course of life all of us spend time in “dark and dreary” places, wildernesses, circumstances of sorrow or fear or discouragement. Our present day is filled with global distress over financial crises, energy problems, terrorist attacks, and natural calamities. These translate into individual and family concerns not only about homes in which to live and food available to eat but also about the ultimate safety and well-being of our children and the latter-day prophecies about our planet. More serious than these—and sometimes related to them—are matters of ethical, moral, and spiritual decay seen in populations large and small, at home and abroad. But I testify that angels are still sent to help us, even as they were sent to help Adam and Eve, to help the prophets, and indeed to help the Savior of the world Himself.
