The author is apparently a Mormon, although he does not say so. He repeats the Mormon teaching that men will become gods of their own planets and will father the future inhabitants of those planets.
If man travels to other worlds, how many generations before those offspring are no longer Earthlings but have become extraterrestrial?
I’m puzzled that you would say this. Every reference in the article is from the Bible. Don’t you believe the universe exists and there are stars, galaxies, and planets in uncountable trillions upon trillions?
So, when the Bible says Jesus created the universe, are you thinking he created something different than what we see? When God gave his Son the universe for an inheritance (John 3:35; Heb 1:2; 2:10), are you thinking of some other universe? What other universe is Jesus to have complete dominion over (1 Cor 15:25-28; Eph 1:9-10,20-23) unless it is this one?
When the true Christian is promised that we will “reign together” with Jesus (2 Tim 2:12) and share EVERYTHING he is and has (Heb 3:14) and sit together with him on his throne (Rev 3:21), how exactly do you understand it if you believe this universe of ours exists? How else can any honest Christian interpret these powerful passages about our God and of his divine promises to those who faithfully follow him?
If you do not believe what the Bible says about God’s promises to the true Christian, that’s up to you. But I do not think it is fair to credit Mormons with having a monopoly on biblical truth.
