Paul tells the Thessalonians to "always rejoice" (I Thess. 5:16). How could they always rejoice? How can we?
I have always had a fascination with astronomy, particularly with new discoveries in astrophysics. I watch all the astronomy programs shown on the Science Channel and read the popular Astronomy magazine. Generally speaking, the TV programs deal with recent astronomical discoveries and the interpretation of observed phenomena. I find these programs stimulating.
