The kingdom of God is divine information connecting people into a network called the internet. Every person in the network is a website, such that the kingdom is a World Wide Web (WWW) of people.
A website could be a square, a circle, an octagon, a hexagon, etc. This means that the kingdom could be a net of squares, a net of hexagons, a net of octagons, etc.
The kingdom is published online and everyone that is able to access, study and understand what it means is connected to others like him that are doing the same thing. They may not know each other, but they are united by divine information.
God's kingdom manifested online because the kingdom has no specific location. It is not in the Middle East, Africa, Europe, etc. It has no physical address, physical place of worship or building. It is not found in a Mosque, a Church or a Synagogue.
"I did not see a temple in the city". (Revelation 21:22)
God's kingdom is for God to reign alone. It is the fulfillment of the promise of freedom and absolute liberty. He reigns in you such that you are a king or queen wherever you are.
Christ manifested on the internet because he is here for those that are searching for him. The search engines will take you to where you will find the divine knowledge that will unite you to others like you that belong to the kingdom.
"Unto them that look for him shall he appear the second time" (Hebrews 9:28) "KJV"
Remember that the Temple is the United Monarchy. Since you are the Temple of the living God, you are the United Monarchy if you are educated on what the kingdom is about. You reign because of what you know.
