An "unsaved Christian" is definitely an oxymoron ... I take your statement to mean, if Christians ultimately have been saved from God's wrath through trusting in Christ's substitutionary death, and therefore will never forever perish in the Lake of Fire ..... then why all the warnings to Christians in the NT?
This is the way I see it ... Salvation is secure, the promises of salvation are there to encourage the faint hearted and discouraged. The warnings are there to awake the complacent, presumptuous, backsliding or sinning. God utilizes both blessings and warnings [as well as His hand of chastening] in order to fulfill His promise to preserve all of His children [
John 6:37-39].
The following question is carefully and specifically framed to represent my Molinist viewpoint :
Q: Can a genuine believer lose salvation?
A: Yes.
Q: Will a genuine believer lose salvation?
A: No.
It is one thing to state that something is possible and impossible at the same time, and quite another to say that although a circumstance is possible ... that it must necessarily [at least in one single instance] actuate or come to pass ... the former claim is simply nonsensical. My Molinist position asserts that just because a circumstance [with it's accompanying consequences] may occur ... it simply will not occur in the case of a genuine believer.
"Salvation is secure. The promises of salvation are there to encourage the faint hearted and discouraged. The warnings are there to awake the complacent, presumptuous, backsliding or sinning. God utilizes both blessings and warnings in order to fulfill His promise to preserve all of His children [
John 6:37-39].
To illustrate using the warning label on lawnmowers. Manufacturers are lawfully required to mark an easily seen warning that says something along these lines, "DANGER!! ... KEEP HANDS AND FEET AWAY TO AVOID SERIOUS INJURY OR DEATH" ...
(1) What is the purpose of the warning? ... to prevent serious injury or death.
(2) Is it logical or coherent to assert that any person will or must actually place their hands or feet under the lawnmower in order to make the warning real? ... I don't believe so.
(3) Whether or not a person complies with the warning does not do away with the actual consequences that accompany failure to do so.
(4) Whether or not, and which persons, which actually fail to heed the warning(s) and suffer the real consequences is an entirely distinct question.
(5) The warning passages [scattered throughout the scriptures] are just one of the many means that God utilizes to preserve His children safely into their Heavenly inheritance.
The above truth statements contain some of the most essential premises contained in the Molinist "can/won't model of perseverance". It's the model which I believe best answers the question of "what do we do with the various warning passages we find throughout scripture?"
