Yes—Israel will return to the Mosaic Law system during the Tribulation, but in a corrupted form resembling the Judaism of Christ's day rather than the original Sinai covenant.
Les Feldick states plainly that when the Tribulation begins, Israel will be back under the Law, and the Church must be removed because Law and Grace cannot be mixed (Clip 4). The temple will be operating (Clip 1), and at the midpoint the Antichrist will enter it and shut down worship, forcing Israel to worship him instead of God (Clip 0).
Daniel 9:27 — Describes the seven-year covenant and the midpoint cessation of sacrifice and oblation, implying temple worship under the Law resumes.
Romans 11:25 — Shows Israel's blindness is only until the fullness of the Gentiles comes in, after which God again turns to Israel.
Scripture points to a restored temple and sacrificial system during the final seven-year period. Daniel 9:27 describes a prince who confirms a covenant with Israel for one week and then causes the sacrifice and oblation to cease in the middle of that week. For that language to make sense, the temple and its worship—central elements of the Mosaic Law—must be functioning again. Romans 11:25 shows that Israel's hardness is not permanent: it lasts only until the fullness of the Gentiles comes in. This sets the stage for God to turn back to the covenant people, though the verse itself does not detail the legal form Israel will adopt.
Les Feldick is explicit: 'when the Tribulation begins, Israel will be back under the Law.' He bases this on the unchangeable principle that you cannot mix Law and Grace. Since the Church lives under Grace and Israel will be under the Law, the Church must be taken out of the way (Clip 4). He clarifies that this return to law will not be the pure Mosaic system given through Moses. Instead, it will be 'much the same kind of religion as Judaism was during Christ's earthly ministry'—a religion that has Israel claiming to worship the God of the Old Testament while actually not being a work of God (Clip 1). The temple will be rebuilt and operating, with priests and utensils ready (Clips 0 and 1). At the midpoint, the Antichrist will enter that temple, commit the abomination of desolation, shut it down, and demand that Israel worship him (Clip 0).
According to Les Feldick, it will not be the pure Mosaic Law. He says the religion will be much the same kind of religion as Judaism was during Christ's earthly ministry. This means a temple operating with priests and utensils, but not a system in which God is actively working (Clip 1).
Les argues that God cannot mix Law and Grace. Because Israel will be under the Law at the Tribulation, the Church—which is under Grace—must be removed. He also applies Romans 11:25: when the fullness of the Gentiles is come in, God turns again to Israel (Clip 4).
At the midpoint of the seven years, the Antichrist will turn on Israel and go into the temple. Daniel says he will cause an abomination and make the temple desolate. He shuts down the temple worship and forces Israel to worship him as their Messiah (Clip 0).
Antichrist's Temple Abomination
Les teaches that at the midpoint of the seven years, the Antichrist goes into the temple, causes an abomination that makes it desolate, and forces Israel to worship him instead of the God of the Old Testament.
Judaism Returned, Not Pure Mosaic Law
Les answers that the temple religion in the Tribulation will not be a work of God but 'much the same kind of religion as Judaism was during Christ's earthly ministry.'
Why Peter Preached to "Ye Men of Israel" (Acts 2 & 3 Explained)
But they've been in a dispersion now for 1,900 and some years, and now they've come back in our generation, and everything is getting set for the day when God's once again going to pick up where He left off with His covenant people, Israel. Oh, it's coming, and we're getting closer every day. The world is just rushing, I maintain, to this end-time scenario.
Revelation 20 Explained: Satan Bound, the Millennium & Final Judgment
It just seems as though everyone has gone under the pagan influence that began at the time of Abraham. A difference? Absolutely! Everything is different. God is going to turn His back on all the other nations of the world, and He's going to deal with the one little nation that comes from this man, Abraham.
Israel Back Under the Law; Church Must Go
Les states explicitly that when the Tribulation begins, Israel will be back under the Law. Because you cannot mix Law and Grace, the Church has to be taken out first.
Ezekiel 37 Explained: Israel's Dry Bones Prophecy Fulfilled?
Not like that old covenant of law, but a new covenant, where no one will have to be taught the Word of God. No one will have to be told what the law commands. But under that new covenant, every Israelite will just have the heart of God within them. They will be an obedient people. They will be a people of faith and believing.
Is the New Covenant for Israel or the Church? Jeremiah 31 Explained
I will be their God, and they shall be My people." Now that isn't going to be a choice of Israel. That company of Jews aren't suddenly going to say, Well we've decided to follow God. No, no. But when Christ returns and sets up His Kingdom, that remnant of Jews that He has kept through that tribulation period, will see Him coming in the clouds of glory.
The 3 Parts of the Law & Why They Don't Save You
And so I'm going to take the time, before we go any further in Genesis, so if you'll come back with me to Exodus chapter 19, and we'll pick up the nation of Israel as they've come out of the land of Egypt, they've now been under bondage, remember, and by virtue of the miraculous power of God, they've come out of Egypt across the Red Sea, and they're gathered now around Mount Sinai, and in the very…
Daniel 9:27: 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.
Shows temple sacrifice and oblation are active during the seven-year period, implying Israel has returned to a law-based temple religion.
Romans 11:25: For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
Les cites this to show God must turn back to Israel after the Church is removed—a turning that includes Israel returning to the Law.
Romans 3:20: Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
Les references this passage when discussing the Law given to Israel and its universal relevance.
Isaiah 66:8: Who hath heard such a thing? who hath seen such things? Shall the earth be made to bring forth in one day? or shall a nation be born at once? for as soon as Zion travailed, she brought forth her children.
Les uses this to show the believing remnant of Israel will be born as a nation in a day when Christ returns, transitioning from the tribulation to the New Covenant.
Les says no. It will be a religion resembling the Judaism of Christ's day, heavily altered from the original. The temple will be operating, but God is not working in it in that way.
Because Israel will be back under the Law, and God cannot mix Law and Grace. The Church, which is under Grace, must be taken out so God can resume His dealing with Israel under the Law.
The Antichrist goes into the temple and causes an abomination, shutting down temple worship and forcing Israel to worship him. Israel realizes he is not the Messiah but the opposite.
