Some people may be interested in what the Christadelphians believe, but be reluctant or unable to attend lectures. The Internet gives them an easier method to find out about our beliefs. The Internet makes it much easier for Christadelphians to communicate with each other. Christadelphians living in isolation are considerably less isolated when they can communicate with other Christadelphians quickly and easily every day. The Internet makes this possible.
All technology has the capacity for good, or for evil.
Printing presses can be used to publish Bibles, or they can be used to blasphemy. The problem, generally speaking, lies with the people who use the technology not the technology itself. Of course some technology has greater capacity for evil than others - it is hard to see what good torture equipment can do. I believe that, like printing, the Internet is morally neutral. Like printing, the Internet is here to stay, and like printing Christadelphians can use the Internet in a very positive way.
