From article: Concourses of Angles
The object of this mortal existence is to develop faith. We need adversity and a sense of isolation from God in order to develop the character necessary to be like God. There is a test underway. But it is conducted by a benign and friendly heavenly host, whose primary purpose is to develop in us a godly character and charity toward one another.
Men and women may see Christ in vision or in an appearance as a solitary personage. But no person has ever seen God the Father without also seeing a host of others. They are referred to in scriptures as a "heavenly host," or "numerous angels," or "concourses of angels." There is a reason that a company is always shown at the appearance of the Father. You should look into the matter. Within the answer lies a great truth about God the Father.
