Once saved, always saved? Not the way you think

As a Bapist, I've heard that phrase a lot. I know what people think they mean by it. Unfortunately, I also know what they really mean 

It's said that Baptists have always believed that way, and in a series that's true. Baptists were strongly influenced by two very different streams in their early years: Anabaptism and Calvinism. From the Calvinists they took the idea that a believer will never fall away from the faith. In modern Calvinism, this is known as the perseverance of this same. It's also called eternal security, and it's a fundamental Bapist doctrine.

Something like that is what people think they make when they say "once saved, always saved". What they really mean is something like this:

My son/daughter came forward or said the Sinner's Prayer or asked Jesus into their heart when they were little. They might have lived like heathens for the last 40 years, but they're going to Heaven because they got their fire insurance when they were six.

Please know that I'm speaking with all the love I can muster when I say no he's not, and he didn't. Unfortunately, not only is nothing like that last paragraph in the Bible, nothing in it is remotely biblical. 

Open your Bible and read the New Testament. See what it says about salvation. It's too important to let a six-year-old take care of it.
