Davidian has a good ring to it! hahaha
Hmm... the one that you like, is it a big or growing church?
You could possibly reach out to them and see about starting one in your town. And, if they don't like the idea, or feel they have others who could start the church, then you know do start your very own.
I'll let you know if I get one started.
One person I really like is Rick Warren. I think it would be great to start a church and have it grow to an international church. Selling books, doing speeches, etc. Not taking any money from the church, only get paid through books, courses, etc. Not from preaching. And, like Rick, donate 90% of my income.
Right now, I'm thinking of just a small Bible Study group. There's one I watched grow down the street from me. These people just started by putting out a sign in their front yard that said, "Bible Study Friday. Call XXX" I've only seen it grow from there. I really need to stop by and ask them about it. I guess if you put out the sign they will come.
Yeah, advertising can get expensive. I have a marketing background, and sometimes I feel God wants me to use that to help spread his Word and help save souls. Since, all we can do is plant the seed and water the seed.
So, you could advertise the Bible Study and offer a FREE Bible to everyone who attends who doesn't have a Bible. Etc. Then, start a website, mailing list, etc. Or, start the website first and share my experiences and then a Bible Study group. Don't know yet.
Just some of my thoughts.
Oh, and regards to "Most are already established & happy in churches." We're not looking to take people away from their current church, we're seeking the lost. The world is full of lost people, just waiting for someone to come by and show them the way.
