Should the church be mixed with Israel in the tribulation?

No. The church should not be mixed with Israel in the tribulation, because the tribulation is primarily God's dealing with the nation of Israel, not the church. Scripture remains adamant that God is not through with Israel and will fulfill His covenant promises to Abraham, Isaac, and Jacob.

Les explains that you cannot let the church go in and mix up with Israel in the tribulation, because this is God's dealing with Israel, not the church. He emphasizes that the tribulation is primarily God dealing with the nation of Israel. Les also points to Jeremiah 31:35-36, where God says the ordinances of the sun, moon, and stars confirm that the seed of Israel will not cease from being a nation before Him forever. God will not cast off Israel, and He will still fulfill the covenant promises made to Abraham, Isaac, and Jacob.

Is the tribulation for the church or for Israel?

The tribulation is primarily God's dealing with the nation of Israel, not the church. Scripture presents it as the time when Israel's covenant promises come into fruition, and the church cannot be run into that period because the church is not under Israel's covenants; those covenants are Jew only.
