I fail to see the connection.
Besides, they’r right.
If you undergo a Salvation experience but then become an atheist, the experience does not trump the fact that you are an atheist at time of death. Claiming the experience wasn’t real because the person later became an atheist is a self-fulfilling prophesy and therefore irrelevant as an argument. Baptist love to tell people they are going to Heaven.
There are way too many people going to Hell because someone declared them to be Saved based on a prayer and a bunch of water. There is too much hallelujah and not enough fear and trembling.
