I think Calvin is much more smarter than polygamy. If he doesn’t love his wife, he needs to leave her and go to the next one if he does love her then leave the next one alone.
Polygamy is another thing that goes against the order of God and serves no benefit but only to the one. People who live lavish lives on earth in its fleeting moments must equally be invested, if not more, in their eternal life, which goes on forever.
