Joe,
I do not presume to understand what God may or may not do after the culmination of all things prophesied in the Book of Revelation. It stands to reason that an infinite, omnipotent, and omniscient being could have a multitude of plans and projects in mind. Those plans could well include a redeemed and transformed humanity as agents or objects of those plans.
Larkin, however, is using some ideas current at the date of writing, (1921), along with some poor reasoning to support this idea.
The first problem is that in 1921 very little was known about our solar system. Most people believed that the "canals" on Mars indicated the presence of a civilization on that planet. Venus was thought of as a "garden planet" based on its orbital position. Today we know that all the planets are uninhabitible in their current states.
We also know that earth-like planets are either extremely rare or non-existent outside of our own solar system. Two recent books about this are "Rare Earth" by Ward and Brownlee (non-Christians) and "The Privileged Planet" by Gonzales and Richards, (Christians).
Another problem for Larkin's idea is that most galaxies cannot contain life-support planets due to radiation levels. In our own spiral type galaxie life is only possible within a small range of positions. Positions, btw, that describe our own location.
Larkin also makes some logical/theological errors. He wrote, " Think you that God gave his Son to die on Calvary just to redeem a few millions of the human race? Why, He could have blotted them out, as he did the Preadamite race, and created a new race, and Satan would have laughed because he had the second time blocked God's plan for peopling of this earth."
A couple of problems are:
1. Since human beings are the only creation we know of that bears the image of God, Christ died for at least some of them, (limited atonement), or all of them, (as the Bible plainly teaches,
), the value of his sacrifice is not measured by the quantity of objects, but by its inherent quality.
2. What preadamite race? Although this idea has been around a while, the Bible does not mention it, and science has never turned up any evidence of it.
3. Larkin's third argument, about Satan blocking God's plan for peopling of this earth, begs the question, ie, it assumes what it is arguing for and uses it as a premise leading to the same conclusion.
So, in this universe, I don't think so. In a New Heavens and a New Earth...who knows.
Blessings,
