While the Holy Bible has a great amount to say about The Return Of Jesus Christ, it does not provide a specific date for that event. No one knows when Christ is going to return. The Scriptures do however plainly state that the Messiah will return right after the completion of the miraculous 3½ year / 42 month / 1,260 day ministry of His "two witnesses." When they first appear "with power," Christ's return will be 3 years and 6 months away. Those who recognize the two witnesses as the two witnesses (as stated in the Scriptures below, a great many people in every nation on earth are not going to recognize them for what they are) will then know that their Judgment is at hand (see When Will You Be Judged?)
The Two Witnesses, Then An Angel
The two witnesses will be the greatest human Prophets that have ever lived. Much of their ministry will be the partial fulfillment of "this Gospel of the Kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come" (Matthew 24:14 KJV, see also The Gospel of The Kingdom of God), while it will be an angel that completes the prophecy at Christ's return, after the martyrdom (which proves that the two witnesses will be physical humans) of the two witnesses i.e. "I saw another angel fly in the midst of heaven, having the everlasting Gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people" (Revelation 14:6 KJV)
What does the Bible tell us about the ministry, martyrdom, resurrection and ascension of the two witnesses?
"And I will give power unto My two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth. These are the two olive trees, and the two candlesticks standing before the God of the earth. And if any man will hurt them, fire proceedeth out of their mouth, and devoureth their enemies: and if any man will hurt them, he must in this manner be killed. These have power to shut heaven, that it rain not in the days of their prophecy: and have power over waters to turn them to blood, and to smite the earth with all plagues, as often as they will."
"And when they shall have finished their testimony, the beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and kill them. And their dead bodies shall lie in the street of the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified. And they of the people and kindreds and tongues and nations shall see their dead bodies three days and an half, and shall not suffer their dead bodies to be put in graves. And they that dwell upon the earth shall rejoice over them, and make merry, and shall send gifts one to another; because these two prophets tormented them that dwelt on the earth."
"And after three days and an half the Spirit of life from God entered into them, and they stood upon their feet; and great fear fell upon them which saw them. And they heard a great voice from heaven saying unto them, Come up hither. And they ascended up to heaven in a cloud; and their enemies beheld them." (Revelation 11:3-12 KJV)
