Please understand that to signify that these are NOT a literal periods of time. For example, it is a length of time which is not disclosed (for that would mean we would know when the consummation is, and no man knows the day and hour of the Lord's return), it is the WHOLE NEW COVENANT PERIOD. The first half of the week applies to the ministry/testimony of the church to the world for 1,260 days. It will last until God finish building His Church through the testimony of Two Witnesses (elect). This is when the woman of Revelation 12 (Church) was fed away "FROM" the fact of the serpent.
(14) And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.
This is the first half of the week. It is the same period that the testimony of the Two Witnesses of Revelation 11 for 1,260 days. Christ comes out of Israel (woman), and Israel is delivered of this man Child and she goes into the wilderness (world) where she is nourished/fed with the Gospel for time, times, and a half. Why does it say she is nourished for time, times, and a half, and not the full wilderness journey? Because at the end of this time, times, and a half, the SACRIFICE and OFFERING ceases! Why, when Christ sees that His church as secured all Elect He intended to be seal has been sealed by the testimony of Two Witnesses, he will cause the sacrifice and offering necessary for salvation to cease! There is famine, and she is no longer fed away from the face of the serpent. This is when the serpent start making war with her and she is given into his hand for the "other half". This is the time, times and the dividing of time spoken of in Daniel, which lasts until the consummation when the end comes. THe salvation has ended, but there will be believers who are still "alive and remain" will be given into Satan's hand for time, times, and the dividing of times, and THEN the judgment comes.
(25) And he shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time.
(26) But the judgment shall sit, and they shall take away his dominion, to consume and to destroy it unto the end.
This is what in view. Israel (The New Testament church) is assaulted by Satan and his messengers (false prophets and christs) when he is loosed of God, and these place the abomination in the temple (church). This is the apostasy! And they (the Saints, the church) are given in his hand until time, times, and a half. And then the judgment sits, and the end of the world. This mirrors what we read in Daniel 12 of the "power" of the Holy People (believers) being scattered for time, times and a half, when God swore that all would be finished. All are totally consistent with everything else in Scripture. This is as we read in Revelation 11 of the Two Candlesticks/Witnesses/Prophets/Olive Trees being "killed" which is the silence of the Gospel message for the purpose of Salvation. It is a symbolic picture of the Church. They are overrun by many false prophets and christs what Christ warned in Olivet Discourse and she will be given to Satan's hand when he is loosed for 3-1/2 days. Any way you look at it, God is painting the picture that when the testimony (for salvation) is finished (Revelation 11:7), the true church is killed (not physically killed, silenced). That is the language of sacrifice and offering (or the gift) ceasing. The testimony of the church is finished because all Israel who is to be save, HAS BEEN SAVED! In other words, after all Gentiles be coming into covenant Israel, then all Israel shall be saved. After this, because of the overspreading of abomination that stands in the Temple of God (church), they shall make the temple desolate. This is Mystery Babylon! This will last a short season until the consummation. Till the end come, and judgment be poured out upon faithful church who made it desolate. It will remain desolate until the end. This is what I believe is taking place today. Look at the spiritual condition of God's congregations all over the world where false prophets and christs come with their lying signs and wonders and deceive many "professed Christians" thinking that they are saved or serving Christ when they are not!
The final week of Daniel 9:27 has everything to do with God's New Testament Israel, the church. It started with the power of the Two Witnesses to preach gospel to the world until fullness of Gentiles be coming into the covenant tree of Israel, then all Israel (Woman/wife of Christ - Elect from Old and New Testament from the foundation of the Earth shall be saved or secured. When the building of the church is finished, Christ will cause the sacrifice and offering to ease because there is no more salvation for men! And Satan shall be loosened by God to test the faithfulness of His church and the judgment of the unfaithful church will take place prior to Second Coming. This is why God has warned his people that when they "see" the abomination of desolation standing in their church, they should flee and wait for Christ's return. That is where I believe we are right now. Sadly, there are many Christians who believe they will not have to worry about "great tribulation" so they will be raptured out and the rest of the prophecies will have to deal with national Israel and Jews. Boy, they are deceived because they do not realize that it is the Church that is being judged by God and has been warned that this is where the battle of armageddon actually takes place instead of the Middle East. This is why the unfaithful church is a mystery to many who cannot see the signs of Christ's return, thinking its all about national Israel. She is the mystery Babylon the Lord has warned us to flee. But like Lot's sons-in-law, many professed Christians will deny that God would judge their church and that we should not forsake the assembly. Remember Lot's wife!
