Well, it would certainly be a miracle if it happens. The trend is currently in the opposite direction and has been for the past 40 years. There are now five times as many young non-believers than there were 40 years ago with upwards of 20% expressing their non-affiliation with religion.
As a nation we appear to be near the beginning of the same secularization that took place decades ago in Western Europe, and the danger is that if Christians continue to express the same hostility towards non-believers that I have seen on many threads on this board, they will be delivered right into the hands of the left.
Since I’m not a Christian I would prefer to live in a country where conservative atheists and agnostics can live without the constant antipathy non-believers get from the religious right. Political allegiances are hard to maintain when you’re not even considered to be worthy of political office unless you profess belief in a supernatural being.
So what do you make of the prediction from the Bible that “The Gates of Hell will not prevail against it.” (Church)?
Keep in mind however, that many young unbeliever “come home” later in life, especially after they begin to raise families. Also in the past many actual non-believers probably claimed nominal Christianity (but lacked real faith) for social reasons that are less prevalent now. The reality may not be nearly as dire as statistics make it seem.
