The issue is if salvation can be lost. And if one is in the camp you can, then how do they believe Ephesians 2:8-9?
Salvation cannot be lost. Salvation is freedom from physical death. All of mankind will be raised immortal and incorruptible. (1Cor 15:42ff) Death has been abolished (1Ti 1:10) so nobody will stay dead. All of mankind is saved from the grave.
Eternal life CAN be lost. Eternal life is dependent upon whether or not you do the good works which God created specifically for you that you make them you constant manner of life. (the next verse; Eph 2:10)
And I see that it is almost a universal error by Christians to conflate the two concepts.
Salvation from death which is the wages of sin: universal.
Eternal life: only to those who are obedient to Christ.
Using Ephesians 2:8-9 as a "proof text" is an example of the error of picking and choosing which verses a person will use to support his personal opinion.
When Ephesians 2:8-9 was written, Paul did not put any chapter and verse numbers. Those were not added until the 1500s and were inserted for the sole purpose of assisting people in finding passages.
Ephesians 2:8 -9 does not contain the entire thought which Paul was putting forth.
Quoting that is essentially quoting half the truth.
And half the truth can easily be twisted into a falsehood.
In this case the falsehood is that a "saved" person cannot loose their salvation.
Which many people, due to their practice of conflating salvation with eternal life, are confused on this point.
Will someone be saved from the grave and physical death no matter what he does? Absolutely.
Will someone have eternal life no matter what he does? Definitely not. Only those who are obedient to the LORD and do the good works for which God created them to do will inherit eternal life.
And someone who is a believer and is doing those good works but then decides to go back to his old ways of doing the works of the flesh will not be granted eternal life. He will earn the 2nd death. (Eze 19:24)
You have been saved from the grave being your permanent residence. Nothing can change that.
You will attain to eternal life if you do your best to obey the Lord.
You will not attain to eternal life if you ignore His commands to love God, love one another, love your neighbor and even love your enemies.
and that's MY personal opinion.
