A one world government is something that’ll never happen in the next hundred or so years.
None of the governments can get along as it is so expecting a one world one is laughable.
You might consider writing that down on a piece of paper, dating it, and taping it to your fridge. You won’t have long to wait, but I won’t be here to say “Told you so.”
When it happens, please believe in Christ and turn your life over to him.
