Two waves of resurrection

Reading Revelation 20 today, I was a little confused about the order of things to come. It seems that some people will be raised from the dead, and will rule with Jesus for "a thousand years". So far as I can tell, it is those who are martyred that will receive this privilige. These will be "blessed and holy". During this time, Satan is bound and thrown into the abyss.

At the end of the thousand years, Satan is to be released, and after being defeated in battle, all the rest of the dead will be raised and "judged according to what they had done as recorded in the books."

So, in other words, some people get the equivalent of university "early entry". Something to think about.
