The Sinners Prayer - Does it save?

Almost every Pastor in America has used the "Sinners Prayer" to fill their churches. A good portion of the people that fill those churches have relied on this prayer for Fire Insurance. But are they really saved?? Are you really saved?? Is this "Sinners Prayer" even Biblical?? If it's a "Sinners Prayer" that has not transformed you then it will not save you! We don't see the church in America getting or America itself getting any better. So what's the problem? David Platt states, "I'm convinced that many people in our churches are simply missing the life of Christ, and a lot of it has to do with what we've sold them as the gospel, i.e. pray this prayer, accept Jesus into your heart, invite Christ into your life." "Should it not concern us that there is no such superstitious prayer in the New Testament? Should it not concern us that the Bible never uses the phrase, 'accept Jesus into your heart' or 'invite Christ into your life'? It's not the gospel we see being preached, it's modern evangelism built on sinking sand. And it runs the risk of disillusioning millions of souls."
