Eternal security is not in the scriptures. Some text in the absense of other text would result in a figment of OSAS. That is adding and subtracting from the Scriptures. If the doctrine of OSAS requires adjusting the verses, it is sure sign of delusion
2 Thessalonians 2:8And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: 9Even him, whose coming is after the working of Satan with all power and signs and lying wonders, 10And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. 11And for this cause God shall send them strong delusion, that they should believe a lie: 12That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
James 1:13 Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man:
Delusions come from willful blindness of truth. There are many verses that refute OSAS. And granted there are many verses that a support it. Two diametrically opposed statements means one meaning must poetically understood while the other is the core truth. The poetry is the nuance and the hard simple prose must be the core truth as the wriggling would make it nonsensensical. The bible is not nonsense. Bible inerrancy demands it.
I am a married bachelor and a little pregnant.
Because I love you, you can't leave me. (because I gonna use magic handcuffs or I gonna make you love me)
Not one iota of that last analogy relates to this topic.
Eternal Security is scripture. Or, Jesus was a liar, as is God, and Jesus died a failure.
At this stage that is precisely what unbelievers are putting forth. They are unbelievers in the Gospel that teaches God's grace gave us irrevocable eternal salvation by God's choice, not our labors to earn it.
This fact is all through Jesus ministry. It is not diminished by unbelievers in it. It does not become less because unbelievers do not see it.
In fact, unbelievers are a blessing in that their fixation with denying sinners are washed clean forever and are grace filled and irrevocably saved so not to perish as a dead in sin sinner, prove other parts of the true words of Christ.
The natural (sinner) mind cannot understand the things of God. Because they are spiritually discerned.
Those who have the Holy Spirit and are forever saved from perishing under sins, do understand the things of God. Like eternal irrevocable salvation by grace of our Father.
We won't reach those natural minded folk. And they shall never, no matter how many threads they start, shall speak over God's truth of eternal irrevocable salvation.
It is a shame they try. However, it is also a condition afforded sin nature, natural, worldly, minds that think God needs their help and consent to keep his word. That they believe they can overcome by choice and deed at any time. Making human behavior able to overcome divine covenant.
That's sad. And shall always be error.
"OSAS" Isn't heresy. It is divine favor. Unbelievers will never see that. Unless the Holy Spirit changes their mind. Him! Not us.
And that's it.
