Jesus told us His kingdom is not of this earth.<quoted text>So earth is not of gods kingdom? We have been told no human can follow all the rules as we are flawed beings, so is it not futile to aspire to be perfect? Do we really have to be so perfect to get to the supposed gods kingdom?
And I must again point out, if we are all gods, then what is gods kingdom?
And the atonement is how we become perfect. It is not futile to try to be perfect. We must strive to fill the glass of perfection as best we can. The atonement of Christ fills the rest of the cup for us.
God's Kingdom is in Heaven. Not on earth. And yes, you must prepare to achieve it. It is not handed to you.
