A revelation of sorts

What an exhausting day! I'm very tired, today I had language class, met up with a new missionary here and we toured the Prague Castle today....quite the walk. I was on my feet pretty much the whole afternoon. It is quite the hike up to the castle, lots of stairs and incline. We walked through a couple of churches. They are absolutely stunning. They can take your breath away with the grandeur of the building and architecture. Your neck gets tired from looking up at the paintings and statues of these buildings. Then to stand there and look at the size of the building and picturing it being packed full of people. Now this wouldn't be a hard thing to do with all the tourists. However, what about those who are there for the purpose of why it was built in the first place. It was built for the purpose of people gathering together to worship God. What do we see this building as being now? A popular tourist spot, some are still free to go into, why does it cost anything to walk into a church??? This nation seriously needs revival! All of these big grand churches are empty. Empty spiritually and physically, not counting those who walk through there for the sights. I mean there are churches here, but with my church being at about 20 people and the building being shared with another church, just makes me ponder. What truly happened to Christianity that it would die a death to this extreme. Sure I know what happened through history, but seriously were there really only a few Christians who survived this? I know that Christianity is growing, but to think of going back generations just after Christianity just died off, how many would claim they were true Christians who are living by the word and worshiping the one true God. Was there just a handful? Obviously I do not know the answer to this, but these are questions that came to my heart and my mind today while walking around. Please share your thoughts.
