Moving from asking about mockers, as that didn't generate much interest, to this:
Without crystal ball or tea leaves or any witchcraft, tell us the future. Tell us your vision of America in 50 years/the world in 50 years. Be an armchair futurist. Extra credit for everyone if they contrast what the future will be like if:
A: Christ has returned and set up His Kingdom-or
B: He has tarried, and that hasn't happened yet. Those who don't believe in His existence, I guess you would focus more on B. Anyway, share your vision for 2056.
Don't worry about sounding foolish-I've got that market cornered most of the time.
