Based on your question, It appears that you may have a hard time meeting new people. Me too, sometimes! It's scary. You mentioned meeting new Christians. Have you found a good church in your neighborhood? I am a chaplain if that is the direction you want to go. I'm not sure that there are any sites that will provide a list like what you are asking for. Do you have a Facebook page? That might be a good place to start. You can pick and choose who you want as "friends". And you never really have to meet any of them, but you can share your thoughts and things with 12-15 million other people!
Hope this helps
That is the number of people who have access to Facebook. It is inconcievable to think you or anyone could or would want to access everyone of them. having a selection does not mean that you or anyone has to interact with all of them. If you filled out a profile on facebook and listed some of your hobbies or interests, others with the same hobbies or interests could ask you to accept them as "friends" and you could then share ideas.
