Hi - I've done the Alpha Course- I did it at a Baptist Church. I found it interesting but a little bit "right, now you've had the facts. Time to feel the Holy Spirit and say you're a Christian!!"
Fact is, is that I wasn't convinced 100% (and probably never will be) so I didn't really have that urge to suddenly be "born again". There was the pressure to become a full member of the Church. Perhaps it was just because they were Baptist (and fairly evangelical) but eventually after lots of questions they said "look tinylion, you just have to let it all go and have faith"...well, I'm not really like that...although I do believe in good/evil and God.
It basically goes through - who was Jesus?, why he is relevant today?, what Christians believe? How God's love can change your life etcetera. There's a video first and then questions.
I had some questions about validity of virgin birth, why I think Jesus was prophet rather than Son of God, but it didn't really deal with those.
Useful if you are interested in Christianity and want to meet like minded people. Less useful if you have some indepth questions about points of faith.
Hope I've given some useful info - oh, and you usually get a decent meal after the talk!
