Without laughter life on our planet would be intolerable. So important is laughter to us that humanity highly rewards members of one of the most unusual professions on earth, those who make a living by inducing laughter in others. This is very strange if you stop to think of it: that otherwise sane and responsible citizens should devote their professional energies to causing others to make sharp, explosive barking-like exhalations.

Dark energy is perhaps the biggest mystery in physics.

Asthma doesn't seem to bother me any more unless I'm around cigars or dogs. The thing that would bother me most would be a dog smoking a cigar.

Millions of Germans had absolute faith in Hitler. Millions of Russians had faith in Stalin. Millions of Chinese had faith in Mao. Billions have had faith in imaginary gods.

Consider the wave of revulsion that floods the average person when he or she hears of the practice of human sacrifice by the Aztecs and other so-called primitive peoples. How savage and barbaric such practices seem. But when a Christian or Jew comes across human sacrifice in the Bible (see Jephthah's immolation of his daughter in Judges 11:30-40), is he or she repulsed?

Impartial observers from other planets would consider ours an utterly bizarre enclave if it were populated by birds, defined as flying animals, that nevertheless rarely or never actually flew. They would also be perplexed if they encountered in our seas, lakes, rivers, and ponds, creatures defined as swimmers that never did any swimming. But they would be even more surprised to encounter a species defined as a thinking animal if, in fact, the creature very rarely indulged in actual thinking.

There are hundreds of millions who believe the Messiah has come. If he did, then it is unfortunately the case that his heroic sacrifice and death have had no effect whatsoever on the very problem his coming might have been expected to address, for history demonstrates, beyond question, that we Christians have been just as dangerous, singly and en masse, as non-Christians.
