2 Peter 2:1, ". . . denying the Lord that bought them, and
bring upon themselves swift destruction."
Exactly.
False teachers may go so far as to deny the Lord that bought
the people, and bring upon themselves ( the false teachers ) swift destruction.
Also, see this:
" the Lord knoweth how to deliver the godly out of temptations, and to reserve the unjust unto the day of judgment to be punished:
10 but chiefly them that walk after the flesh in the lust of uncleanness, and despise government. Presumptuous [are they], selfwilled, they are not afraid to speak evil of dignities.
11 Whereas angels, which are greater in power and might, bring not railing accusation against them before the Lord.
12 But these, as natural brute beasts, made to be taken and destroyed, speak evil of the things that they understand not; and shall utterly perish in their own corruption;
13 and shall receive the reward of unrighteousness, as they that count it pleasure to riot in the day time. Spots [they are] and blemishes, sporting themselves with their own deceivings while they feast with you;
14 having eyes full of adultery, and that cannot cease from sin; beguiling unstable souls: an heart they have exercised with covetous practices; cursed children:
15 which have forsaken the right way, and are gone astray, following the way of Balaam [the son] of Bosor, who loved the wages of unrighteousness;" ( 2 Peter 2:9-15 ).
Here's how I understand the above:
9) The Lord knows how to deliver the godly ( His elect made so by His power and by the blood of His Son ) out of trials, and to reserve the unjust ( those who do not believe and are not His elect from before the foundation of the world ) to the day of judgement to be punished.
10) Speaking of the false teachers in verse 1...God is reserving the unjust, especially them that walk after the flesh in the lust of uncleanness and despise government.
They are presumptuous, self-willed ( hard-headed ), and not afraid to speak evil of public officials.
11) Comparatively, angels, which are greater in power and might then us mere men, do not bring railing accusation against them before the Lord.
12) These false teachers, as the natural brute beasts to God that they are, were
made by Him to be taken and destroyed.
They speak evil of the things that they do not understand, and they shall utterly perish in their own corruption.
The rest describes the qualities of false teachers... who they are, what they do and where they come from.
So, with all that in mind, how is it that the Lord Jesus Christ, who only saves those whom the Father has given Him ( John 17:2 ) and who gave His life for the sheep ( John 10:11-15 ), also made it possible for false teachers who were specifically
made to be taken and destroyed, to be saved and to be forgiven of their sins through His blood?
I see that He did not, as there cannot be a general atonement for those whom the Lord specifically made to be taken and destroyed.
Therefore,
I conclude that God only casts into Hell ( and reserves for everlasting punishment ) those that His Son did
not atone for, and who hate Him and His Son.
Those that He has afore prepared unto glory ( Romans 9:22-23 ) are those Christ died for, and it was a sure and dedicated work for them and them alone.
