No. One judgment. Scripture speaks of judgment, not a judgment.
Those who are in heave are saints. If we are going toi live in bliss, do you suppose some of us will be more blissful? Is heaven going to be "new capitalism?"
I really don't know. I'm not sure if there will be commerce, but I also don't think our Heavenly existence will be floating by and waving to our friends on the next cloud bank. :) I think we will be "doing" something, and I have no problem believing that different people will be doing different things.
Isn't there a difference between us and the martyrs in Heaven? Why not also among the people in terms of rewards? Jesus said:
Matt 11:11 : I tell you the truth: Among those born of women there has not risen anyone greater than John the Baptist; yet he who is least in the kingdom of heaven is greater than he. NIV
So, by some measurement, we know that in Heaven some are "greater" and some are "lesser". I would think rewards would reflect that.
