The following information relates to the belief that once saved, a Christian cannot 'lose' his salvation. Scripture quoted is from the NIV Bible, not because it is 'best' but because it states these points clearly while still agreeing with the KJV and other universally accepted translations.
Many people fervently believe that once saved, they can never lose their salvation.
I pray that those who do believe it will read the following with an open heart and an open mind. I sincerely believe the 'once saved always saved' concept to be wrong. From my experience, Christians can sin and they often do sin but to believe that a Christian can live any way he or she likes, and still be saved, is dangerous. Some argue that a 'real' Christian wouldn't commit these sins and it is the 'almost Christians' who fall foul of this type of entrapment from the enemy. I believe that would be wrong too.
