"Hypers" deny the free offer of the Gospel. That is the difference.
Now you have been straightened out. The hyer-Calvinist is an absolute (or double) predestinarian just like I am. However, I am also a free offer of the gospel believer which they are not. So, I believe more of the Bible than they do just like I believe more of the Bible than does the Arminian (or anybody who denies predestination).
Until you understand how predestination works with the feet that are shod for the gospel of peace you will not understand why we are mission oriented. Until you quit reading Romans 2 in your wierd way, you will not understand the urgency to preach the gospel of the kingdom.
I was struck 2 days ago when watching the opening ceremony of the Olympics (I had it recorded) that it is likely that we have whole nations and tribes and tongues and people groups (my own blood relatives) who have never been exposed to the gospel of the kingdom.
