"My father replied that he must be mistaken in calling this a new and strange doctrine, that Christ Himself, in His teachings to His disciples, had preached His second advent. He had said: “In My Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again, and receive you unto Myself; that where I am, there ye may be also.” When He was taken up to heaven before their eyes and a cloud received Him out of their sight, as His faithful followers stood gazing after their vanishing Lord, “behold, two men stood by them in white apparel; which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen Him go into heaven.” 1T 41.1"
