That is a very bad interpretation. What? Some of God's people will be raptured and some will not? God is no respecter of persons. And no one can be saved after a "rapture" because the Holy Spirit will not be in the picture. It is the Holy Spirit that draws and convicts the sinners heart.<quoted text>
Of course there will be some of God's people left after the rapture and after the tribulation.
Matthew 25:32 (NKJV)
32 All the nations will be gathered before Him, and He will separate them one from another, as a shepherd divides his sheep from the goats.
I believe you may be reading too many "Left Behind" fiction books.
