“Well with the leakage to other churches, they need the overkill I guess :-)”
The Mormons are not alone in their quest for babies. The “king of the baby mills church is Catholicism.” At least Mormons don’t restrict birth control. But with all of them it’s about membership and money! My Catholic friends growing up used to call sex “Vatican Roulette!”
It’s easy to get cynical I suppose. Even I can.
If you really thought you were smack dab in the middle of a work of God, then I think you’d logically want as many children as possible to be part of it. You might or might not be right about where you are, but you would be right that God wanted it and would bless it.
