We'll have a very detailed look at this in the next few weeks however its important to note that over His entire ministry in the Gospels:
a) Jesus mentions being 'Born Again' just once in John Chapter 3 'privately' at night with a further explanation to the religious theologian Nicodemus.
b) Jesus uses the word “church” (ekklesia) just twice, both in Matthew:
Matthew 16:18 — “I will build My church…”
Matthew 18:17 — “tell it to the church…”
He preached the “Kingdom of Heaven”
✔ c. 66 times and The “Kingdom of God”
in Mark, Luke, and John
These are the differences between The Kingdom of Heaven and The Kingdom of God:
Matthew uses “Heaven” as a respectful Jewish circumlocution apparently Jewish tradition avoided saying “God” directly in everyday speech.
So Matthew — writing to a Jewish audience — uses:
Kingdom of Heaven
instead of
Kingdom of God
This is probably like saying:
“Heaven rules” instead of “God rules”
“Blessed be Heaven” instead of “Blessed be God” It’s reverence, not difference. Mark, Luke, and John say “Kingdom of God as its likely Gentiles did not avoid saying “God,” so the other Gospel writers use the more direct phrase: Kingdom of God (66 times across the Synoptic Gospels)
Same meaning.
Different audience.
Different phrasing.
This is not the whole story as there may be further differences and we'll explore these in much more depth. Its interesting that when Jesus sent out anointed disciples the 12/7/72 He said announce that "the Kingdom has arrived (is here and present)" its from this point of declaration that the atmosphere in all the village changed and there are healing's, deliverance's and miracles so there's are plenty of questions for us to ask not least is why are we not preaching as they did !?.
