Hello OP. It's great that you're exploring faith. But I think that many of the pp on this thread have said it so well: exploring faith is a journey of differing lengths and differing paths according to differing personalities. I love Alpha, I don't think it's crap, because I've been fortunate enough to be in a church which does it well. I've been on the leadership for a few, and they've always been places where questioning is encouraged, where pat answers are not given, where a lot of listening takes place. However, I've heard of courses where it seems a lot more prescriptive and heavier expectations are put on guests, which is a shame. I guess it depends on the church - and how comfortable you feel in it all. But 3 weeks is a very short time, and I really wouldn't pressure yourself to have come to a decision or to have had experiences during that time. It's OK to walk slowly and take it all in.
The experience you had did sound like a touch of God's love and grace :)
There are some great books out there, as others have said - but again, it will depend on what you are looking for. Something more academic or something rooted more in a person's story?
Feel free to post questions and thoughts here, or on the Christian chat thread if you'd like. You're very welcome.
Going back to the gender pronouns: when 'he' is used for God in the Bible, the form of it is gender-neutral, like 'la table' in French - 'he' is simply a word to describe it. It's less than perfect, and for years now scholars have tried to come up with a gender neutral pronoun, but nothing has taken. I find it easy to look past the male pronoun, but understand why others wouldn't, so often try to keep it to 'God', though 'Godself' is a bit clunky. I sometimes mix pronouns instead.
It's not a problem to me because I never see God as exclusively male or exclusively female...
