If you are a GenXer like me, you probably remember how big horror genre was in the 1980s. Omen and that sort of thing. I recall a movie I watched once about some man who wanted to rule the world and used black magic for this. He need a human sacrifice for his incantation to work (yes, he was that evil). It had to be an unbaptised child and in the end, he found a boy from an unbelieving family. It produced so much impression on me that I still remember this detail, many years later...
While I don't wish to start a discussion about paedo vs credo baptism, I'd like to point out that the Scriptures say that the children of believers are holy, which literally means "set apart." That's exactly what the child baptism does, imo. On the other hand, many Evangelical churches still allow rather young children to be baptised, since they believe that even a child of 4-5 years old can be a professing Christian, so it's not a real problem.
The real problem is the fact that many people who were baptised by their parents turned out unbelievers or are, at the very least, indifferent to the matters of faith. They aren't going to baptise their children or to bring them to church or to pray over them or any of these things. And I do believe that it means trouble in the future.
There is this famous Bible verse (Matthew 5:13):
Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted?
Believers have a preserving influence on the society, as the West becomes less Christian we see the very fabric of it being torn apart. And while being baptised won't bring you to Heaven if you don't have a saving faith, since it's a sacrament it still has a protective effect, imo; and not only on the person himself/herself, but on the society as a whole.
You ain't seen nothing yet. Personally I expect things to get a whole lot worse...
