This belief will then move further down the path to claim that any who do fall away were never saved anyway but were mistaken in their belief that their relationship with Jesus was ever real.
This is a common excuse used by those supporting ideas of “Once Saved Always Saved”.
It’s not surprising that those who hold to that view also have no hesitation in believing that they themselves ARE truly saved and would never have their faith exposed as being false by some future abandonment of it. But, apart from pride, can any of them be TRULY sure that their faith is genuine enough to last the distance?
"if you think you are standing firm, be careful that you don’t fall!"
1 Cor 10:12
"Do not be arrogant, but tremble. For if God did not spare the natural branches, he will not spare you either. Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise, you also will be cut off." Romans 11
