You see the preaching of the kingdom on earth as the same elephant as the kingdom in heaven?
Hmmmm.....
Where did you see anything called "the kingdom in heaven?"
"
Kingdom in heaven" .... 0 verses found.
I think I see why you are confused... I am not sure what you are reading, but it is likely that your brain is substituting one phrase (with a different meaning) other than what it actually says in scripture. There is a big difference in meaning between "
in" and "
of."
I am familiar with a different phrase:
"
Kingdom of heaven" ... 32 verses found.
The
kingdom of heaven is established upon the earth, also called the kingdom of God or simply kingdom.
"
Kingdom of God" ... 69 verses found.
Note that Matthew 19:23-24 below (and Luke 18:24-25) establish that "the
kingdom of heaven" and "
the kingdom of God" are just two ways of saying the same thing.
Matthew 19:23-24 KJV
(23) Then said Jesus unto his disciples, Verily I say unto you, That a rich man shall hardly enter into
the kingdom of heaven.
(24) And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into
the kingdom of God.
Also compare Matthew 13:31 with Mark 4:30 and Luke 13:19: Matthew uses "
kingdom of God" whereas Mark and Luke use "
kingdom of heaven" to describe the same parable.
Matthew 13:31 KJV
(31) Another parable put he forth unto them, saying, The
kingdom of heaven is like to a grain of mustard seed, which a man took, and sowed in his field:
Mark 4:30 KJV
(30) And he said, Whereunto shall we liken the
kingdom of God? or with what comparison shall we compare it?
And that
kingdom is established at his coming when he returns to earth, when the dead are raised and made incorruptible to inherit that
kingdom.
2 Timothy 4:1 KJV
(1) I charge thee therefore before God, and the Lord Jesus Christ, who shall judge the quick and the dead
at his appearing and his kingdom;
1 Corinthians 15:50-52 KJV
(50) Now this I say, brethren, that flesh and blood cannot inherit
the kingdom of God; neither doth corruption inherit incorruption.
(51) Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
(52) In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
So yes, when Jesus preached
the kingdom while he was on the earth, that was
the kingdom which he shall establish when he returns from heaven. Luke 19 has a very apt parable to illustrate that
this kingdom is established when Christ returns, and not before.
Luke 19:11-12 KJV
(11) And as they heard these things, he added and spake a parable, because he was nigh to Jerusalem, and because they thought that t
he kingdom of God should immediately appear.
(12) He said therefore, A certain nobleman went into a far country to receive for himself
a kingdom, and to return.
The kingdom is of God because it is of God. The kingdom is of heaven because it is of heaven. Not "inside God" and not "inside heaven" but established from and by the power of and ruled by God and heaven. That's why it says "the kingdom of heaven" and "the kingdom of God" and even "the everlasting kingdom of our Lord and Savior Jesus Christ." (2 Peter 1:11).
2 Peter 1:11 KJV
(11) For so an entrance shall be ministered unto you abundantly into
the everlasting kingdom of our Lord and Saviour Jesus Christ.
Luke 1:31-33 KJV
(31) And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS.
(32) He shall be great, and shall be called the Son of the Highest:
and the Lord God shall give unto him the throne of his father David:
(33)
And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end.
Isaiah 9:6-7 KJV
(6)
For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor,
The mighty God, The everlasting Father, The Prince of Peace.
(7) Of the increase of his government and peace
there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this.
These are all the same thing. There will be One kingdom, one God, one Lord, one Spirit, one Christ, one body, one faith, one baptism.
Ephesians 4:4-6 KJV
(4) There is one body, and one Spirit, even as ye are called in one hope of your calling;
(5) One Lord, one faith, one baptism,
(6) One God and Father of all, who is above all, and through all, and in you all.
