Also, study who the elect are in the new testament. That should help you see that it's the church, not unbelieving Jews.
I do not believe that any of us "pre-tribbers" are saying that "the elect" being spoken of in Matthew 24 are "UNBELIEVING Jews". NO!
Rather, ones who will have come to faith IN / DURING / WITHIN the trib yrs being spoken of there (FOLLOWING "our Rapture")... It is THEY who will be DOING the "inviting TO" the promised and prophesied earthly Millennial Kingdom (aka "the wedding FEAST")... in the form of Matt24:14 / 26:13 (and 22:9-14... which follows sequentially [/chronologically] from what was stated about "the 70ad events" in v.7 of that passage);
Matt24:29-31 corresponds with Isaiah 27:12-13 (all entirely earthly-located... to where Jesus will at that time be heading down to: "the earth," FOR the promised and prophesied earthly Millennial Kingdom).
