The church is the body of Christ. The Kingdom is God’s domain of heaven. In the New Testament, the kingdom coming is God’s revelation of the second coming of Jesus as told in Revelation. Each of the passages you included all point to this; none of them point to the church being the kingdom. The church is necessary or the holy spirit to inhabit the hearts of worshipers through Jesus Christ. Without communion with other Christians, the holy spirit cannot take root and grow.
“none of them point to the church being the kingdom.”
I’m sure glad you noticed that too because I went through all of Scriptures and was saying to myself they refer to Jesus Christ Himself, not His church.
All we have to do is look at Acts 1:6-8, Jesus clearly says that it’s not for you to know when the kingdom will be established v.7, but then He indicates when His Church will be established, v.8.
When we investigate v.6 we see that the kingdom is when Jesus Christ sits on His father David’s throne, Isaiah 9:7, Luke 1:32-33 in Jerusalem and establishes His earthly kingdom and rules with a rod of iron, Rev 2:27.
Acts 1:6-8
6 So when they had come together, they were asking Him, saying, “Lord, is it at this time You are restoring the kingdom to Israel?” 7 He said to them, “It is not for you to know times or epochs which the Father has fixed by His own authority; 8 but you will receive power when the Holy Spirit has come upon you; and you shall be My witnesses both in Jerusalem, and in all Judea and Samaria, and even to the remotest part of the earth.”
Jesus is the King of this spiritual kingdom.
15 And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel.
(Mark 1:15 KJV)
43 And he said unto them, I must preach the kingdom of God to other cities also: for therefore am I sent.
(Luke 4:43 KJV)
2 And he sent them to preach the kingdom of God, and to heal the sick. ... 60 Jesus said unto him, Let the dead bury their dead: but go thou and preach the kingdom of God.
(Luke 9:2, 60 KJV)
9 And heal the sick that are therein, and say unto them, The kingdom of God is come nigh unto you.
(Luke 10:9 KJV)
28 There shall be weeping and gnashing of teeth, when ye shall see Abraham, and Isaac, and Jacob, and all the prophets, in the kingdom of God, and you yourselves thrust out.
(Luke 13:28 KJV)
By the context the Kingdom of God then are the saved ones in heaven and the ones on earth,
the church saved by the gospel preached since Eden,
the promised seed that should crush Satan,
the redemer, Genesis 3:15.
The gospel that Abraham foreknew,
when he prophecy that in the mount God sould provide of sacrifice,
not the provisional ram foreshadow of the messiah, but Jesus!
7 And Isaac spake unto Abraham his father, and said, My father: and he said, Here am I, my son. And he said, Behold the fire and the wood: but where is the lamb for a burnt offering? 8 And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together. 9 And they came to the place which God had told him of; and Abraham built an altar there, and laid the wood in order, and bound Isaac his son, and laid him on the altar upon the wood. ... 13 And Abraham lifted up his eyes, and looked, and behold behind him a ram caught in a thicket by his horns: and Abraham went and took the ram, and offered him up for a burnt offering in the stead of his son. 14 And Abraham called the name of that place Jehovahjireh: as it is said to this day, In the mount of the LORD it shall be seen
. (Genesis 22:7-9, 13-14 KJV)
Traduction of NKJV:
14 And Abraham called the name of the place, The-LORD-Will-Provide; as it is said to this day, “In the Mount of the LORD it shall be provided.”
(Genesis 22:14 NKJV)
The kingdom of God began with Christ’s death and resurrection and must be further extended by Christians until it has been brought into perfection by Christ at the end of time, the kingdom of God is in the here and now, present in and through the Church. Yet it is a mixed reality that will only be perfectly realized at the end of history. This current “mixed” state can be seen as the Church on earth which now grows in the field of the world with both weeds and wheat until the harvest when Christ says he will “tell the reapers, Gather the weeds first and bind them in bundles to be burned. But gather the wheat into my barn” (Matt 13:30).
