Kingdom of Heaven vs Kingdom of God
As I am reading the book of Matthew, these two terms keep poping up. Some claim these two terms are much the same, just being used in different time and setting.
To me, Kingdom of Heaven is something that Jesus said in chapter 11, "forcifully to enter". It is something that we have to do, just in chapter 3, "repent".
But the kinddom of God is somewhat different. It starts in chapter 12 that Jesus first directly mentioned, or possibly in chapter 6, "seek His kingdom and His righteousness..."
Re: Unknown
No idea what was said in the destroyed posts, but I might suggest that the Kingdom of Heaven could be thought of as, for want of a better word, that which is currently the afterlife, wheras the Kingdom of God could be more a state of subjugation to His will. This would make one a place to enter and the other a state to seek.
But of course the difference may be purely a result of idiomatic differences during translation.
