I'm not sure that's a fair assessment. I think the difference in view is a question of discernment. A Born Again Christian will believe Roms. 10:9 that if you confess with your mouth the Lord Jesus and believe in your heart that God raised Him from the dead, you will be saved.
I'd like to say the Holy Spirit within us confirms our security because that seems to be true in my case but there are many who, tho indwelt by the Spirit do not have that confirmation...
So I then just turn to the scriptures and get (have gotten) my confirmation there...Losing my salvation has never been an issue with me...
