I hope that God strikes them dead so they can’t reproduce.
No matter how hard they try, "Bobby" and Donna aren't going to reproduce.
Please tell me you didn't actually bend God's ear with that "prayer". We too often forget that the slightest sin carries the same penalty and we were just as "dirty" as the worst that the world has produced before we allowed Him into our hearts. It might be better to pray that they come to a point where they ask Him to wash away their sins that they might live in His Glory and warm His Heart.
