There is much internal criticism about this.
It boils down to whether the prayer is sincere. If it’s not sincere, don’t pray it.
It is vacuous. It completely skirts the issue of whether the “repeater” really thinks they need a Savior. If you don’t think you need a Savior, what’s the point?
But of course, I am colored by my Methodism where you can always Fall from Grace so the prayer doesn’t ensure anything.
Also every Baptist I have met recently come across as Reformed. They define “Once Saved Always Saved” as classical “Perseverance of the Saints”. Strange.
