The seven year great tribulation, which is not found anywhere in scripture, was derived by mans misinterpretation of Daniel 9:24-27. This is what the Bible clearly reveals about the seventy weeks. From vs.24 to vs.27 was seventy weeks or 490 days beginning with Ezra, (Ref: Ezra Chapter 3-6), rebuilding the temple to the time of the Messiah (Jesus Christ) being fulfilled in his birth, death and resurrection. In a sense it was a literal and spiritual temple that was being built. Ezra was teaching the people of the Spiritual temple of God that indwelled in all that believed in God and of the coming of Messiah. There was actually a five hundred year span from Ezra till the birth of Jesus that God shut himself off from National Israel because of their transgressions towards the Lord, but saved a remnant that would believe in the coming of Messiah, (Ref: Isaiah Chapter 10), as still today, God waits for National Israel (all people of the world) to repent and believe in the name of Jesus.
Daniel 9:24-27 the Vision of the Seventy Weeks
Vs. 24 Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.
This verse shows us that the timing from Ezra to the cross was 490 days as within that time Ezra was reestablishing the law in Jerusalem until Jesus had fulfilled the end of transgression, made an end to sin, made reconciliation for iniquity and bring everlasting righteousness and to seal up the prophecy to fulfill the law through the cross.
Vs. 25 Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times.
From the time of the cross, which also means the last days, which includes what some like to separate and call the Great Tribulation, which is not mentioned anywhere in scripture and is not a separate event after the elect of God are caught up, but as the last days so we are in tribulation times until the end of the world as we know it; (Ref: Acts 2:17; Hebrews 1:1,2; Matthew 24:4-31; Mark 13:24-31; Luke 21:5-36). These are just some of the scriptures that support that we will go through all things of Revelation Chapters 6-21 (Please read these chapters). Everyone will have opportunity to come unto salvation through Jesus Christ if they would only repent, but when Satan is cast into the lake of fire forever after the second battle, which will be explained later in this chapter, that will come out of Jerusalem Gods judgment will be upon his people and the books will be opened at that time. No secret rapture as the saints of God are still here at this time.
Matthew 25:10 and while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut.
Vs.26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined.
After 434 years that end in the year AD29 shall Messiah be cut off. Jesus was crucified after he was baptized in AD 29 three and a half years later. Jesus was cut off (killed) by the people of the prince, which means National Israel or other words the Pharisees, Sanhedrin and the high priest that destroy the city and the sanctuary (meaning Christ) and the end thereof shall be with a flood (Gods wrath) that will put an end to abominations by desolation or in other words a ruin to evil deeds. Daniel 9:27 explains the definitions of desolation of abominations or the ruin of evil deeds. There is no actual Desolations of Abominations where the so-called Antichrist will take a literal throne, but the desolation will be when the final Pope tries to take his throne in Jerusalem, (Ref: Daniel 11:36-45). Gods’ word never defines one great Antichrist, but says there are many antichrists. The seven years that some call the seven year tribulation means three and a half years of Jesus teaching before he was crucified and three and a half years of Stephen teaching before he was stoned to death, which took place after Jesus was taken up to heaven.
1John 2:18 Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time.
2Thessalonians 2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
2Th 2:2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
2Th 2:3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
2Th 2:4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
2Th 2:5 Remember ye not, that, when I was yet with you, I told you these things?
2Th 2:6 And now ye know what withholdeth that he might be revealed in his time.
2Th 2:7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.
2Th 2:8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:
2Th 2:9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders,
2Th 2:10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
2Th 2:11 And for this cause God shall send them strong delusion, that they should believe a lie:
2Th 2:12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
Vs.27 And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
The 70th seven began with Christ baptism in AD 29 and three years later at the end of the first half of the 70th seven sacrifices and offering ceased because Christ hung on the cross as he was the final sacrifice that fulfilled the law. From the giving of the law in 458BC when Ezra went to establish the law, or to rebuild the Spiritual city right up to the cross were the first 69 sevens. The 70th seven is from the time of the cross until Jesus comes and gathers his bride as they prepare to stand in the Holy place until the overspreading of abominations he will make desolate, or make an end to all that would not repent.
