I was raised with a couple different approaches to Christianity, first the boring going to church every Sunday sitting between my parents and listening to the droning of the pastor, then in my teens introduced to the “exciting” world of evangelicalism. Long story short, there’s so many interpretations and means which people have used the Bible to control and abuse, I can’t support many of the “Christians” or their churches based off of their messages and their actions.
Instead I just live my life best I can with the foundational messages and what I think God really wants of me - to be in service, love, and support others to the best of my ability. I’m a massage therapist that works in hospice. I make a modest living bringing comfort and kindness to others. I also volunteer at a food bank every month. My Jewish boyfriend isn’t religious, but culturally follows many Jewish traditions. Which oddly enough makes his behaviors and lifestyle line up much closer to my own values than any other “Christian” man I’ve dated in my 51 years.
While there may be those who feel called to drop everything and travel to spread the word - you’re right, economically it wouldn’t fly. If I did that, ultimately my welfare would be reliant on creating a burden for others. As long as I can continue to provide for myself, I can use any additional resources and time I have to help and support others.
