Can we get rid of that word 'unsaved'? People can became done and undone, happy and unhappy, employed and unemployed, healthy and unhealthy, ambitious and unambitious.... etc. etc. etc. But one thing that a person can't become 'un' (or lose) is their salvation. Yes I know that many here will argue that point but scripture points to the obvious.... once Christ saves an individual, that person can never be plucked from His hand. There is no such thing as 'unsaved'. Very simply, there is the 'saved', and there is the 'lost'.
Unsaved simply means someone who has not been saved. At least not yet if they are yet to obey the Gospel. Naturally, someone can continue in that state to the bitter end. It is certainly fully accurate to call them “lost” ... if I could know who was which.
If you want to generally use the term “lost” that too is fine. But then you have the opposite issue I’ve got, that when dealing with those who have yet to obey you might consider use of the qualifier “presently” because you (or I) don’t know how this will play out for them.
That, BTW, is why I couldn’t use “not yet saved” when talking about the presently lost because that might be taken as me affirming something more than is justified.
I try not to do that if I’m able.
I predict folks will NOT 'argue', but post SCRIPTURE that says you CAN lose it!
