All the warnings are for us to ever remain on guard against recapture by Satan.
Such loss is in this present life by slaveship to sin and it's wicked unseen master.
The warnings have nothing to do with loss of eternal salvation.
So you just make up your own interpretation of what the clear and undeniable scriptures say.
12 Beware, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God; 13 but exhort one another daily, while it is called "Today," lest any of you be hardened through the deceitfulness of sin. 14 For we have become partakers of Christ if we hold the beginning of our confidence steadfast to the end,
Hebrews 3:12-14
we have become partakers of Christ if we hold the beginning of our confidence steadfast to the end,
If a believer departs the living God, before the end, then there is no promise that remains for him to be a partaker of Christ.
The end of you faith is the salvation of your soul.
1 Peter 1:9
We receive the promised salvation at the end, not the beginning of our faith.
... if we hold the beginning of our confidence steadfast to the end.
If we have faith in Christ for salvation, then we have the substance of the thing we are hoping for.
The reality of this promised salvation, comes on the Day of Judgement when these words are spoken to -
'Come, you blessed of My Father,
inherit the kingdom prepared for you from the foundation of the world: Matthew 25:34
Until you here these words, you are still operating in faith for Salvation, and you are told by Jesus Christ, the Author and finisher of your salvation, to endure to the end.
Be faithful unto death and I will give you the crown of life.
Paul said it this way -
yet now He has reconciled... if indeed you continue in the faith, grounded and steadfast, and are not moved away from the hope of the gospel which you heard.
21 And you, who once were alienated and enemies in your mind by wicked works,
yet now He has reconciled 22 in the body of His flesh through death, to present you holy, and blameless, and above reproach in His sight-- 23
if indeed you continue in the faith, grounded and steadfast, and are not moved away from the hope of the gospel which you heard, which was preached to every creature under heaven, of which I, Paul, became a minister.
Colossians 1:21-23
Peter said it this way -
8 whom having not seen you love
. Though now you do not see Him, yet believing, you rejoice with joy inexpressible and full of glory,9
receiving the end of your faith--the salvation of your souls. 1 Peter 1:8-9
This beautiful salvation is laid up for those who believe, and believe to the end.
