Interestingly, I ran across a Catholic (RCC) article last week that also distinguished between the KOH & the KOG. I wish I'd saved the link, and I didn't look at it closely. I was searching a protestant topic, and that article didn't really address what I was looking for so I moved on.
Seems to me the critical issue vis a vis
Kingdom of Heaven vs Kingdom of God
is which is a subset of the other.
But I don’t know that even that is critical.
What is and what will be . . . is thoroughly out of our hands
EXCEPT THAT WE CAN CHOOSE TO RECEIVE CHRIST’S BLOOD, SALVATION AS A TICKET TO BOTH.
In a way, it seems to me that Heaven is a subset of the Kingdom of God if one construes all that is—the Kingdom of God.
Then there’s that former missionary to the Amazon who’s name I can’t recall and haven’t been able to find on the net . . . prayed and fasted off and on for 7 years to be able to go to Heaven and return to tell about it—claimed to have spent 5 earth days in Heaven . . . and that Heaven was a sphere a million miles in diameter . . . Interesting bunch of narrative, in any case. We shall see.
Blessings,
