The Old Testament is full of stories where a nation blessed by God decide that they like new gods better and that the old God isn’t worthy of worship anymore. The New Testament talks of people falling away and being led astray before Jesus returns. What America is doing is not new and is not a surprise and I think there will be a lot less Americans in heaven than we thought there would be.
The world holds few surprises for most Christians. Threats to the faith and to the faithful come in all sorts of forms, from apostasy to overwhelming hostile forces, be they spiritual or human, but they are all of the same origin.
We know we have an enemy and he is manifested in unfolding earthly events and from the heart of the evil man. Increasingly this enemy (the author of confusion and chaos) seems to be stirring.
Americans just aren’t taking their kids to church anymore. I see it every time we are at church. What people forget about when they raise kids is that if a child is not exposed to Christ and his teachings as a kid than they will not act like someone who has good morals when they are an adult. Also the divorce factor comes into play as well.
