What will happen to Israel during the tribulation period?
The mass of the nation will become apostate and follow their leader, the antichrist (John 5:43, see Q 20). A small remnant, though, will be raised up by the Lord. Their trust in Him is expressed in the Psalms, and their suffering during this period is evident from Matthew 24:15-30; etc. They will preach the gospel of the kingdom to the whole creation (Matt. 24:14).
