Pattern is Prophecy
Acts 1:6 When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel? 7 And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power. 8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. 9 And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight. 10 And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel; 11 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.
Imagine that the Lord's ministry is a pattern. That the beginning of this age began with His ministry, followed by His ascension. This then ignites the second stage which is the ministry of the Apostles Peter and Paul.
Now at the end of the age you have the rapture of the saints which also ignites the third stage which is the ministry of the two witnesses during the first three and a half years of the tribulation while all those seeds that never germinated or never fully reached maturity now sprout and bring forth fruit with a tremendous revival.
That concludes with the two witnesses being killed and then ascending before the whole world, igniting the fourth stage, the salvation of the nation of Israel.
