so many church buildings empty and abandoned...does this mean they were preaching something other than TRUTH??

You got that right! They don't preach and let the Holy Spirit lead anymore. The Bible says in the end days, there would be a great falling away in the churches and I think that's what we're seeing now. And it's been that way for quite some time. It's sad. But it also said people in general, would become more vile and immoral and they definitely have. They are more disrespectful and violent these days.

Yes I think you are right
