2 advents of Jesus Christ:
Purpose of the Great Tribulation – driving the Jews to the wall until they acknowledge their offense, which was rejecting God at His 1st coming (His offer – Matthew 4:17, their rejection – Matthew 12:24), and requiring them to seek Him for His 2nd coming. – Hosea 5:15
Satan targets believing Jews in particular because if he wipes them out no one will be around to seek God for His 2nd coming.
