And arrives far in the future:
Matthew 7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Matthew 7:22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
Matthew 7:23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
So, there is a day coming that people will come to Christ and claim they have the right to enter the Kingdom but he will refuse them. The kingdom is in the future according to this.
Matthew 13:45 Again, the kingdom of heaven is like unto a merchant man, seeking goodly pearls:
Matthew 13:46 Who, when he had found one pearl of great price, went and sold all that he had, and bought it.
Matthew 13:47 Again, the kingdom of heaven is like unto a net, that was cast into the sea, and gathered of every kind:
Matthew 13:48 Which, when it was full, they drew to shore, and sat down, and gathered the good into vessels, but cast the bad away.
Matthew 13:49 So shall it be at the end of the world: the angels shall come forth, and sever the wicked from among the just,
Matthew 13:50 And shall cast them into the furnace of fire: there shall be wailing and gnashing of teeth.
Matthew 13:51 Jesus saith unto them, Have ye understood all these things? They say unto him, Yea, Lord.
Have you understood these things? The Kingdom comes "at the end of the world" when there shall be a separation of the good and bad. The bad will be destroyed. The Kingdom is being likened to judgement, where the wicked die and the just will receive eternal life!
