I believe they do not understand that the Tribulation is for the purpose of having Israel finally turn to Jesus.
They see it as His dealing with all mankind, but it is specifically for Israel.
Correct. The seven years of the tribulation are the last seven years of the 490 allocated to Israel as seen in Daniel. It’s to make an end to sin and bring Israel back to God. The church has been taken out and God deals with unbelievers as a way to get Israel to turn to Him.
