Arlene,
 
Just wanted to post your ponderings of the millennium again:
 
What I do think is that the purpose of the Millennium is the last test of man's inherent wickedness. In the Book of Job, the argument was between Satan and God that there was not a righteous man who would not turn from God when tested ! in all areas. But, Satan was allowed to work on Job in this testing. In the end, Job was rewarded seven-fold. However, "man" has not yet been tested in a world with perfect rule without interference from Satan. Would man again fail and prove there is no inherent righteousness in him? Yes, it would prove man would fail even in a world of perfect rule under Jesus Christ.....Satan will be released and still be able to deceive people at the end. So, God will prove that His judgment at the end is righteous beyond argument.

I had to smile when I read this because just a little over a week ago, I was talking with my husband about this very thing.  I also had wondered if- the your reason stated above -was the reason for the 1000 year reign.  Of course I didn't know that it was your thoughts at that time, I thought they were unique to me because I couldn't remember hearing or reading it stated like that before. 
 
But just to retain my uniqueness, I do believe in the single pretrib. rapture of the church. :)
