There have been many such messengers over the ages, manifesting through one or another of the great world religions or followed by a new form of religion based on the new revelation. Divine revelation and the periodic appearance of messengers, or Avatars, occur, however, according to cosmic law, when certain conditions exist within the whole scheme affected by, and affecting, every part, large and small. Then a chain of events is set in motion which under law must eventually work out.
The imminence of the reappearance of the Christ is sensed and expected by many, belonging as He does to all humanity irrespective of differing religious dogma and doctrine. “He for whom all men wait” will Himself determine the manner and the timing of His appearance and the area of his work in a way which creates no divisions or separations between men, either religious, social or ideological. Not only does He come as the first Son of God, but as Head of the spiritual Hierarchy, the inner government of the planet. He is, therefore, a great world executive, representing the Kingdom of God, and fulfilling a definite function in the world of men. He is coming to establish through precept and example in world service the principles on which a united, interdependent and interactive world may create its new material systems and spiritual institutions for the new civilisation.
Preparation for the second coming is the responsibility of humanity; it is for those who know and accept the imminent return of the Christ to prepare men’s minds and hearts to recognize and receive Him, and to create those conditions of balance and spiritual alignment which will ultimately draw Him forth into our midst. For no matter what message or revelation the Christ may embody when He comes, no matter what principle or energy He may anchor on Earth for human use, He is not coming to save humanity from the results of its own sins, but once more to show humanity how to save itself in the new conditions and new opportunities with which the world is faced.
