The Parker Pen Company recently ran an advertisement pointing out that their new fountain pen was much cheaper than a computer 'mouse'. Books are probably cheaper than the telephone bill for the internet and can be put in your pocket and taken on holiday. Above all, books can be kept and re-read.
What books are worth re-reading? I have just re-read the seven-volume Life of Hudson Taylor by Dr. A.J. Broomhall. But although I enjoyed it hugely, I am not sure whether I can recommend it as it is out of print. But what a fascinating read as Hong Kong goes back to China.
Hallesby on Prayer is worth re-reading. My copy dates back to student days but I still read it from time to time. The language may seem dated but that does not destroy its worth. The very fact that it comes to the subject at an unexpected slant makes us stop and think, and reconsider just what prayer is and how we approach it.
