How many kingdoms does Scripture describe and when will the one kingdom be set up?

Scripture describes only one kingdom, not multiple. That one kingdom will be set up on earth when Christ returns to become King of kings and Lord of lords. It is spiritual, physical, and political, and it will come to its fruition at His return.

Les explains that all through Scripture there is only one kingdom, and it is the kingdom Christ will set up on earth when He returns as King of kings and Lord of lords. He clarifies that this kingdom is not merely spiritual, ethereal, or invisible; it is also spiritual, physical, and political. It will come to its fruition when Christ returns and sets it up on the earth. Les notes that when Jesus said the kingdom is within you, He meant that an inner spiritual relationship with God is necessary to become part of that literal, physical, political kingdom one day coming on the earth. He also connects this to John 3 and being born again to see the kingdom of heaven, which is the same kingdom that will be on earth.
