[Revelation 10:7 NLT] (7) When the seventh angel blows his trumpet, God's mysterious plan will be fulfilled. It will happen just as he announced it to his servants the prophets."
The blowing of the seventh trumpet is spoken about as the arrival of "the Kingdom of our LORD and of his Christ" in the next chapter:
[Revelation 11:15 NASB20] (15) Then the seventh angel sounded; and there were loud voices in heaven, saying, "The kingdom of the world has become [the kingdom] of our Lord and of His Christ; and He will reign forever and ever."
It is a secret with many sub-secrets:
[Matthew 13:11 NASB20] (11) And Jesus answered them, "To you it has been granted to know the mysteries of the kingdom of heaven, but to them it has not been granted.
[Luke 8:10 NASB20] (10) And He said, "To you it has been granted to know the mysteries of the kingdom of God, but to the rest [they are told] in parables, so that while seeing they may not see, and while hearing they may not understand.
[1 Corinthians 4:1 NASB20] (1) This is the way [any] person is to regard us: as servants of Christ and stewards of the mysteries of God.
It is said by Jesus to be so secret/mysterious that one must be born of God in order to recognize it:
[John 3:3-5 NASB20] (3) Jesus responded and said to him, "Truly, truly, I say to you, unless someone is born again he cannot see the kingdom of God." (4) Nicodemus said to Him, "How can a person be born when he is old? He cannot enter his mother's womb a second time and be born, can he?" (5) Jesus answered, "Truly, truly, I say to you, unless someone is born of water and [the] Spirit, he cannot enter the kingdom of God.
It is so mysterious that although it arrived 2000 years ago, most Christians, though apparently converted, still think of it as some future thing, that will not come about until some future return of Christ.
But Jesus made it plain that the time of the arrival was in the first century, not the 21st!:
[Mark 1:15 NASB20] (15) and saying, "The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel."
But it arrived invisibly:
[Luke 17:20-21 NASB20] (20) Now He was questioned by the Pharisees as to when the kingdom of God was coming, and He answered them and said, "The kingdom of God is not coming with signs that can be observed; (21) nor will they say, 'Look, here [it is!]' or, 'There [it is!]' For behold, the kingdom of God is in your midst."
The sign of Jesus' coming and the arrival of the Kingdom of God was linked by Jesus over and over with the judgment/destruction of the Temple, Jerusalem and the Jerusalem Temple Sinai covenant based Jewish theocracy:
[Luke 17:23-30 NASB20] (23) "And they will say to you, 'Look there,' or, 'Look here!' Do not leave, and do not run after [them.] (24) "For just like the lightning, when it flashes out of one part of the sky, shines to the other part of the sky, so will the Son of Man be in His day. (25) "But first He must suffer many things and be rejected by this generation. (26) "And just as it happened in the days of Noah, so will it also be in the days of the Son of Man: (27) [people] were eating, they were drinking, they were marrying, [and] they were being given in marriage, until the day that Noah entered the ark, and the flood came and destroyed them all. (28) "It was the same as happened in the days of Lot: they were eating, they were drinking, they were buying, they were selling, they were planting, [and] they were building; (29) but on the day that Lot left Sodom, it rained fire and brimstone from heaven and destroyed them all. (30) "It will be just the same on the day that the Son of Man is revealed.
[Luke 21:20-22 NKJV] (20) "But when you see Jerusalem surrounded by armies, then know that its desolation is near. (21) "Then let those who are in Judea flee to the mountains, let those who are in the midst of her depart, and let not those who are in the country enter her. (22) "For these are the days of vengeance, that all things which are written may be fulfilled.
[Matthew 21:41-45 NKJV] (41) They said to Him, "He will destroy those wicked men miserably, and lease [his] vineyard to other vinedressers who will render to him the fruits in their seasons." (42) Jesus said to them, "Have you never read in the Scriptures: 'The stone which the builders rejected Has become the chief cornerstone. This was the LORD's doing, And it is marvelous in our eyes' ? (43) "Therefore I say to you, the kingdom of God will be taken from you and given to a nation bearing the fruits of it. (44) "And whoever falls on this stone will be broken; but on whomever it falls, it will grind him to powder." (45) Now when the chief priests and Pharisees heard His parables, they perceived that He was speaking of them.
So what is the Kingdom of God? It is Christ and God's People fused together in a New Covenant. In the NT it is variously described as:
- the True Vine and its branches
- the Good Shepherd and his Sheep
- the New Jerusalem
- the Christ and his Bride
- the Head and the Body
- the City on a Hill
- the Temple Made Without Hands, comprised of Living Stones
- the House of Prayer for All Nations
- the Dwelling Place of God
- the Father God and his Sons
- the Israel of God
Etc., etc., etc...
If you can "see" this then you are in on the Secret of God:
[Matthew 13:11 NKJV] (11) He answered and said to them, "Because it has been given to you to know the mysteries of the kingdom of heaven, but to them it has not been given.
[Luke 8:10 NKJV] (10) And He said, "To you it has been given to know the mysteries of the kingdom of God, but to the rest [it is given] in parables, that 'Seeing they may not see, And hearing they may not understand.'
