Revelation 12 and the first part of 13 shows me a 7 year period of time which is the great tribulation when all of Israel (the woman) will be saved, Romans 11:25-27. And Gentile Christians (the rest of their offspring) will be present. (No pre-trib. secret rapture)
That is nonsense, for in Revelation 13, John very clearly tells us that the Beast will only have 42 months and not 7 years and which is yet another thing that proves your churches interpretation of Daniel 9:27 to be false.
For all mentions of the 3 1/2 years or the 42 months, or the time, times and a half of time or 1, 260 days are speaking of the same 3 1/2 years and no where does it tie any of them together to make 7 years.
Also, 70 weeks of years in Daniel 9:24-27 is all about what Jesus would do from the start of his ministry which was 3 1/2 years and then in the Middle when he put to rest (shabboth) the OT sacrifices and offerings by his own and then beginning the last 3 1/2 years at his resurrection and ending at Paul's conversion.
This is when he confirmed the Covenant in his blood with the many leaders of his church for us who would read their testimony about it in the scriptures.
For many of your churches teach falsely that there is a gap between the first 69 weeks and that last week and that the antichrist is the one who makes a 7 year covenant and then breaks it in the middle of the week and which is total nonsense and also false.
For one thing, Daniel doesn't tells us that he only makes a covenant but that he confirms the covenant for a full 7 years and there is no way for one to confirm a covenant for 7 years and then also break it in the middle of the seven years.
Look up the words in the Hebrew, for to confirm means to make it powerful and strong, for 7 year.
Now concerning your mistranslation of Paul's words about Israel in Romans 11, you need to go back to the context of chapter 9 and the first verses that Paul wrote on this, for he very clearly reveals that he is not speaking about ethnic only Israel being saved but rather all of the children of the promise and which now also includes the Gentile believers.
Notice also, For Paul very clearly reveals that there is only one Olive tree in which the natural branches that were broken off in unbelief are now grafted back in by faith and also the branches of the wild Olive tree of the Gentiles are grafted into the same single Olive Tree that is Israel of the promise and the Spirit.
Paul basically says the same exact thing in Ephesians 2:11-22 and as I have included below.
Ephesians 2:
11 Therefore, remember that formerly you who are Gentiles by birth and called “uncircumcised” by those who call themselves “the circumcision” (which is done in the body by human hands)— 12 remember that at that time you were separate from Christ, excluded from citizenship in Israel and foreigners to the covenants of the promise, without hope and without God in the world. 13 But now in Christ Jesus you who once were far away have been brought near by the blood of Christ.
14 For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility, 15 by setting aside in his flesh the law with its commands and regulations. His purpose was to create in himself one new humanity out of the two, thus making peace, 16 and in one body to reconcile both of them to God through the cross, by which he put to death their hostility. 17 He came and preached peace to you who were far away and peace to those who were near. 18 For through him we both have access to the Father by one Spirit.
19 Consequently, you are no longer foreigners and strangers, but fellow citizens with God’s people and also members of his household, 20 built on the foundation of the apostles and prophets, with Christ Jesus himself as the chief cornerstone. 21 In him the whole building is joined together and rises to become a holy temple in the Lord. 22 And in him you too are being built together to become a dwelling in which God lives by his Spirit.
Romans 11:
13 I am talking to you Gentiles. Inasmuch as I am the apostle to the Gentiles, I take pride in my ministry 14 in the hope that I may somehow arouse my own people to envy and save some of them. 15 For if their rejection brought reconciliation to the world, what will their acceptance be but life from the dead? 16 If the part of the dough offered as firstfruits is holy, then the whole batch is holy; if the root is holy, so are the branches.
17 If some of the branches have been broken off, and you, though a wild olive shoot, have been grafted in among the others and now share in the nourishing sap from the olive root, 18 do not consider yourself to be superior to those other branches. If you do, consider this: You do not support the root, but the root supports you. 19 You will say then, “Branches were broken off so that I could be grafted in.” 20 Granted. But they were broken off because of unbelief, and you stand by faith. Do not be arrogant, but tremble. 21 For if God did not spare the natural branches, he will not spare you either.
22 Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise, you also will be cut off. 23 And if they do not persist in unbelief, they will be grafted in, for God is able to graft them in again. 24 After all, if you were cut out of an olive tree that is wild by nature, and contrary to nature were grafted into a cultivated olive tree, how much more readily will these, the natural branches, be grafted into their own olive tree!
Paul couldn't have made it any clearly, for OT Israel is a thing of the past and it will no more be revived, for the NT Israel is of the Spirit and the Promise and it also now includes both Jew and Gentile and both of these texts reveal this also.
One Olive Tree which is Israel and consisting of the both natural branches that at one time were broken off and which are not being grafted back into by faith and then also the branches of a wild Olive tree now also grafted into that same single Tree of Spiritual Israel by the same faith.
