We believe Jesus was inspired by God, so what does then the Kingdom of God is upon you mean?
Matthew 12:28 “But if it is by the Spirit of God that I drive out demons, then the kingdom of God has come upon you.”
Remember the words of John the Baptist and Jesus: “
Repent, for the kingdom of God has come near.” (Matthew 3:1-2, 4:17)
The Kingdom is now, in our hearts, because we have access to the Holy Spirit and Christ reigns in our hearts even now. Jesus made the kingdom available to all. The Kingdom starts in us when we accept the word of God. And Jesus is the Word made flesh.
Let’s look at Matthew 13:19 “When anyone hears the message about the kingdom and does not understand it, the evil one comes and snatches away what was sown in their heart. This is the seed sown along the path.”
So aside from the message here, we can see that the word (message of the kingdom) preached by Jesus (about His messiahship and salvation) was sown in the hearts of the people, and they must understand it and accept it for it to take root in their hearts. And then the Kingdom of God will reign in their hearts.
I don’t know how to interpret dreams, but perhaps let the ground (that the rosaries were being sown in) be your heart. And then the Word and Truth will take root in you and spring forth blossoming into salvation. And the Kingdom of God will reign in your heart. And remember, a kingdom usually has a king and a queen, Jesus and Mary
The “city” you wanted to build may have represented the Kingdom of God. But instead of buildings, it starts in the heart, and by planting the Word in your heart. So to build the kingdom, the rosary (and word of God) planted in your heart is the first step.
