To be quite honest, I've never read much on Luther.
The understanding of eternal life is evident in reading the Word.
He who believes in the Son has eternal life, but he who does not obey the Son shall not see life, but the wrath of God abides on him. John 3:36
And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up; that whoever believes may in Him have eternal life. John 3:14-15
Sure sounds like John was talking about an assurance of salvation.
Also, I notice how you've attempted to stray away from the topic of this thread....the immaculate conception.
Perhaps it's because you cannot scripturally defend the immaculate conception. Even rcc apologists admit they can't.
And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up; that whoever believes may in Him have eternal life. John 3:14-15
Sure sounds like John was talking about an assurance of salvation.
You have given a perfect example of what I was talking about. Read those two Scripture verses again. They are talking about the FACT of salvation. There is no reference whatever to the SUBJECTIVE emotional state of "assurance."
Are you capable of reading those verses without seeing something that ISN'T THERE?
I thought I had made clear, but I’ll say it again:
I DON’T CARE that the Immaculate Conception is not explicitly taught in Scripture.
I DOES NOT BOTHER ME that the Immaculate Conception is not explicitly taught in Scripture.
The reason for this is that I reject the self-contradictory, man-made, un-Scriptural doctrine of sola scriptura, which is not taught in Scripture.
