It is unbelievable how Lee's teaching can make the most simple passages in the bible the most complicated! (which enables only his works and publications to decode them...)
To understand this verse alone one must read it in the context of verses 44-49:
The contrast here between the natural body and the spiritual body follows from their two representatives in (vs. 21-22). One is the first Adam who had a naturally body (of dust-Gen 2:7) and through whom a natural body is given to his descendants. The other is the last Adam, Christ, the life-giving spirit (John 5:26) Who through his death and ressurection will at the second coming give his redeemed people a spiritual body similar to Christ's ressurected, glorified body!(LK 24:36-43, php. 3:21, 1 John 3:2)
This passage gets me excited!
This is our hope and future! There is not much to debate here...
