WHEN? It may be today! The Word of God does not tell us; but we read that "the coming of the Lord draweth NIGH" (Jas. 5:8), and again, "Surely I come QUICKLY" (Rev. 22:20).
WHY? In order to take His blood-bought ones, dead and living, to be where He is. Hence we read that "the dead in Christ shall rise first: then we which are alive and remain shall be caught up together with them in the clouds,... and so shall we ever be with the Lord" (1 Thess. 4:16, 17). And again, "I will come again, and receive you unto Myself; that where I am, there ye may be also" (John 14:3). Notice, the word "ye" excludes mere professors such as the "foolish virgins" of Matthew 25.
HOW? "The Lord Himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God" (1 Thess. 4:16). "Behold, I come quickly" (Rev. 3:11). Thus He comes in Person-"the Lord Himself."
WHERE? The meeting place shall be in the air, and not on earth. The Lord shall descend; they shall "be caught up... to meet the Lord in the air." Such is the appointed trysting-place.
WHITHER? To the Father's house on high, the heavenly home of the children of God, to the prepared mansion above, and the joys of the eternal presence of the Lord. (See John 14:1-3.)
