“Once saved, always saved is an error that even many Protestants have a hard time with.”

Ephesians 1:13:

And you also were included in Christ when you heard the word of truth, the gospel of your salvation. Having believed, you were marked in him with a seal, the promised Holy Spirit.

1 Peter 1:23

For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God.

2 Corinthians 1:22

Set his seal of ownership on us, and put his Spirit in our hearts as a deposit, guaranteeing what is to come.

And is it even possible to achieve sufficient enought works to earn salvation? The answer is no:

Isaiah 64:6

But we are all as an unclean thing, and all our righteousnesses are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away.

You are jousting with windmills my friend because the scripture verse you cite don't make your case. All you have here is philosophical speculation about what they imply. If justification cannot be lost before death then St. Peter would be dead wrong to suggest that: Therefore, brethren,be all the more diligent to make certain about His calling and choosing you; for as long as you practice these things, you will never stumble; 11for in this way the entrance into the eternal kingdom of our Lord and Savior Jesus Christ will be abundantly supplied to you. 2 Peter 1:10 If faith without works assures election and you can't lose that election, then diligence would be meaningless.
