The Internet Evangelism site is an extensive resource for inspiration and instruction for sharing your faith online. Each year they celebrate Internet Evangelism Day with a special focus on sharing your faith using the tools technology makes possible. This year the celebration is on April 21, but the resources available on the site are useful all-year round.
I haven't been able to do as much as I wanted to with IE Day this year (coming between Easter and Mother's Day is a bit of a communication challenge for U.S. churches), but the site itself and the resources on it are one of my most highly recommended resources for churches. As I was looking over the current resource list I found a new one to me: http://www.yesHEis.com. This site has an unusual approach in that it isn't a typical "apologetic site" where you hammer people with truths about the Christian faith.
Not that there is anything wrong with that approach--sometimes it is exactly what is needed (as a drill sergeant's daughter I've been known to use that at times)--but not always--this site has a totally different approach.
Here is how they describe themselves and below it is a very brief video explains it.
We here at yesHEis exist to help you share your faith online. Whether it be a new video that shares the gospel, helping to answer the tough questions that come back your way, or exposing new technology you might find helpful, we’re here to help in any way we can.
Here is the URL for the site: http://www.yesHeis.com
We are told to be "all things to all people that we might win some" as we communicate our faith and this is a great tool to help us do that.
