Apparently the same Anonymous commenter pointed out that the verse says "all" and stated:
"you don't beleive that "in Christ shall all be made alive" spiritually ... ."
Actually I do. Re-read the post, particularly the part that explains who "in Adam" and "in Christ" modify two different "all"s.
The "all in Adam" is the human race descending from him naturally, and the "all in Christ" are the elect.
You would understand that "all" was being modified if I said "all who have Christ as their savior," wouldn't you? or if I said "all in the Lamb's Book of Life"? I wonder why you have trouble understanding that here.
It's a simple Scriptural concept: if you died with Christ (i.e. if He represented you on the cross) then you will be raised with Christ.
