Listen...Matthew 24:29-31 makes it very clear that the gathering of the elect will occur AFTER the days of tribulation that are coming upon the Earth shortly before the Lord returns. Until any of you address this scripture you are just "spinning your wheels". Please address these simple verses or i will move onto another topic.
G:
I think it can be acknowledged usefully that at various times God has been dealing in sovereignty both with Israel and with the church. So there is a sense in which the term 'elect', at different times, can apply to both. In Ephesians 1, for example, God's sovereign purposes are seen with regard to the church. In Romans 9, 10 and 11, for example, we see them in relation to Israel.
When we speak of the Lord's return, it can also be usefully distinguished whether the aspect of His coming relates to taking up His church in the clouds (1 Thess. 4), or whether it with a view to executing His judgment and reign upon the earth. The Matthew passage has a strong Jewish background, in any case.
