The Master had so effectively instructed the Apostles concerning His assured death and His later return to earth in power and glory, that they eagerly inquired as to the time and signs of His coming. (See Matt. chap. 24). Though they failed to comprehend the full import of His reply, He told them that many great developments would intervene between His departure and return; but as to the certainty of His advent as Judge, and Lord, and King, Jesus left no excuse for dubiety in their minds. Throughout the apostolic period the Lord's coming was preached with the emphasis of inspired and convicting testimony. Book of Mormon prophecies concerning the great event are no whit less explicit. To the Nephites the resurrected Christ preached the Gospel of salvation; "And He did expound all things, even from the beginning until the time that He should come in His glory." (Book of Mormon, 3 Nephi 26:3). Questions of supreme import to every one of us are these: (1) When will Christ come? (2) What shall be the purpose and attendant conditions of His coming? The date of the Lord's advent has never been revealed to man, nor shall it be. Prior to His resurrection Jesus Himself did not know it, as witness His words: "But of that day and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father." (Mark 13:32). In the present age the Father hath declared: "And they have done unto the Son of Man even as they listed; and He has taken His power on the right hand of His glory, and now reigneth in the heavens, and will reign till He descends on the earth to put all enemies under His feet, which time is nigh at hand. I, the Lord God, have spoken it, but the hour and the day no man knoweth, neither the angels in heaven, nor shall they know until He comes." (D&C 49:6-7). In the light of such scriptural affirmations we may dismiss as empty conjecture all alleged determinations as to the precise time of the Lord's appearing. Nevertheless, the specified signs and conditions by which is shown the imminence of the event are definite, and from these we know that the great day of the Lord is very near. So near is the consummation that the intervening period is called "today"; and on the morrow mankind shall rejoice or tremble at the presence of the Lord. (See Doctrines and Covenants 64:23-25). Christ's advent shall be made with the accompaniment of power and great glory. While in suddenness and unexpectedness to the unobserving it shall be comparable to the coming of a thief in the night, it shall be a manifestation of surpassing glory to all the world: "For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be." (Matt. 24:27).
