Yep, you are correct. We need to each deal with the Christian nature of our own lives and that of our fellow congregation and let God deal with the "state of the church". We are called on to evangelize the good news, God will take care of the rest. There will always be exactly as many saved Christians in the pews as God wants there to be at that point in time. Not one more or less. Paul instructed Timothy to preach the Gospel "in season and out of season". So, he knew there would be times when the Gospel would be "out of season". There have been many such seasons over the years and we know at the end there will be a great falling away. But until then we just walk the walk, talk the talk and instead of trying to save the world, just try to save your own neighborhood. If everyone only focused on that then the rest would take care of itself.
If good people had learned to say "NO" to evil the evil of the Holocaust would never have happened... and that's just one example. God will deal with the state of the Church... you're right circlecity... Our job is to deal with the 'state of our own souls'...
