What words of encouragement would you give those who are in GCM, hunger for something more, but don't know what else to do since it's been their lives for so long?
Get out. Then go find a Bible-believing church that does not have all the baggage of GCx. Talk with people on this list. Keep reading the Bible and praying.
Get out? That won't help if you are not ready to leave.
There are no words that will sound encouraging and not sound threatening at the same time.
The only thing you'll lose by staying at a GC church is your earthly life. Your salvation will be fine. The same can be said for any other Bible believing/teaching church.
There is no simple, easy, emotionally satisfying answer as any of us can attest to.
