Personally I feel that God is still around helping us shape and orchestrate our lives. I presume that's theism?
Yep. It's a broad term, so if you wanted you could probably find some standard adjectives to add on.
however the thing with Asians are the boy of the family are suppose to carry on some sort of legacy (like last name, religion, etc) and if I convert I'll be sorta abandoning my bloodline.
Ahh, I got it. Well, if you start moving more towards Christianity, don't feel like you have to navigate this all by yourself - see if you can learn from people who have been in your situation.
I hope I don't come off as ignorant or sexist, and I'm sorry if I do, but those rules mentioned in those verses only seem to apply to women. So I'm genuinely curious why is it important for men in relationships (in this case me) to be Christian? I haven't read up much about this so I apologise in advance if I missed something out.
No worries. Go check out the entire chapter - there's a lot of rules and suggestions about marriage there, and there's about as many for men as women. The last rule there - widows who remarry should only marry a Christian is only directed towards women, but the 2cor7 bit could cover the other half. (And also, it is very important for Jews to only marry other Jews. So 1cor7 has a lot of rules, but it's a huge redefinition of what marriage should be.) I'm not sure why that command to women is explicitly in there. I wonder what family and household rules were like in the Empire - I wonder if a Christian man would be able to take part in the life of the church, even if his non-Christian wife didn't approve, but a non-Christian man would have more power to keep his Christian wife away from the church. In a lot of places like this in the NT, Paul is trying to help his churches work out a new kind of life that is Jewish-ish but with major differences, within a much bigger and potentially unfriendly Roman society.
Nevertheless thank you so much for the encouragement and input.
You're very welcome!
