On page 211 of your book Heaven, you ask, “Whom will we rule?” and then go on to say other people, angels and that God may create new beings for us to rule. Are the “new beings” just part of your imagination or is there a scriptural basis for that thought?
This was just my imagination. I actually said “If God wishes, He may create new beings for us to rule.” We know that we’ll rule (I Corinthians 6). When scripture talks about ruling over cities the presumption is people living in those cities are other human beings.
We’ll also rule over animals (to rule means to have dominion over) and I was just throwing out another possibility.
