they are there
Print by (I have this hanging in my home) Annie Henrie
“God has used angels as His emissaries in conveying love and concern for His children. Time in this setting does not allow even a cursory examination of the scriptures or our own latter-day history, which are so filled with accounts of angels ministering to those on earth, but it is rich doctrine and rich history indeed.
Usually such beings are not seen. Sometimes they are. But seen or unseen they are always near. Sometimes their assignments are very grand and have significance for the whole world. Sometimes the messages are more private. Occasionally the angelic purpose is to warn. But most often it is to comfort, to provide some form of merciful attention, guidance in difficult times.”
