Please indulge me while I tell you my story. If you want to skip my history and go to my advice/lessons-learned, skip to the next paragraph... I grew up in a Brethren church in Pennsylvania. After graduating college and getting married we moved out of state and ended up joining a fairly large (~1000 people) Southern Baptist church. We spent about 19 years there and had many wonderful friends, but then because of my job we moved out of state and joined another church. After a few years there we discovered that the pastor was a pedophile, so we left for another church. It was good, and we developed some good friendships there. For reasons I'm not quite sure of, though, we left and joined another church. We developed some friends there too, but the church governance seemed to be at odds with biblical guidelines, so we left. We then went a few months w/o a church and ended up going to a church that really didn't feel right, but it was better than nothing. We were just "pew sitters", though, and didn't really get involved; nor did we make any friends. We left in search of a church where we could be involved again, and joined a church of another denomination. After a while there, the doctrinal differences between the Bible and what they had implemented were too great so we left. We're now again at a fairly large non-denominational church where I hope we can stay.
Personally, I think we skipped around too much. I was very picky and wanted a church that was 100% on point with every biblical doctrine. I still think that doctrine is supreme, but there are a few areas where I'm now willing to compromise on the "small stuff". We also lost a lot of friends because we switched so much. It takes years to build friendships for us, so every time we switched, there was an investment lost. (We just lost touch with our old friends after a while.) I also wanted a place where I could use my spiritual gifts, and some churches didn't have room for that. Now I'm content to use them as God opens doors.
My advice is to be careful about switching too much. Your primary decision should be, is this where God wants me? If you can't tell, though, then ask yourself how your current church is doing, doctrine-wise. You'll also want to assess if you can comfortably serve and be served. And don't forget about the friendships. How would you feel about losing the friendships you've developed at that church? I think switching churches is a big decision and should be met with much prayer and patience.
