I'm not sure, Wally.
I came to Christ at the age of 12 during preaching in an IB church in 1978, so I've seen a lot.
But I no longer attend visible churches like I did back then or even like I did 20 years ago.
That said, I have a couple of questions for you:
1) Does it have to be a visible church on a street corner, or can it be a group of God's children meeting in, say, someone's home?
The latter might take some bit of not only digging, but a lot of prayer to find.
2) What do you think that liberty gives believers the freedom to do, given God's commands in Galatians 5?
For example, to me, Christian liberty means I can take
a drink, but I wouldn't do it in front of my bothers and sisters.
Personally, growing up as an "IFB", I saw many things preached against that when I was a young believer I took exception to, like worldly music.
Now that I'm older and having studied His precious words for many years now, I see that many forms of music are not God-honoring, and are simply borrowed from the world so that everyone can "get a groove" on.
Many things I saw preached against and that I thought "too restrictive" when I was in my teens, I now see in my fifties as not only vital, but something that God commands
every believer to do ...because those are things He is going to judge the lost for.
Most of those are behavioral in nature.
I've seen church splits based on modern music vs. the old hymns ( which I now value highly and completely throw out "CCM" ), and I've seen pastors dismissed by those who want to "progress" and "be more freely expressive" ( to me, that's a different way of saying they want to enjoy the things of this world, which I've had a lot of experience in doing ), and are willing to do anything to get it.
I've also seen Independent Baptist churches who cannot seem to get away from "Hyles-ism", nor do any of the members appear to progress further than milk in their doctrines, nor does anyone seem to care about studying God's word.
As it is, I think the last time I was in a church that actually preached anything
resembling sound doctrine was when I was 39 or 40...and I will be 54 on Friday.
Mostly what I see nowadays ( especially in my own area ) are churches, IB / IFB or no, that aren't interested in the details of Scripture, but are more interested in getting the "program" completed, getting church over and going out to dinner and a movie... or going home and watching the football game.
People getting excited and praising the Lord for His grace and mercy, and for His abundant gifts of this life...for always delivering them out of their troubles and comforting them during their trials?
Taking the Bible seriously and actually wanting to obey the Lord's commands?
No.
To me, those kinds of churches, if they are not already gone, are close to dying out altogether.
Doctrinally sound churches?
I don't think I've ever been in one that preached the
entire counsel of God's word, but some were what I would call, "in the ballpark".
I wish you well in your search.
