Welcome to the boards.
2 Peter 2:20-22 - For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.
Those who are truly born of God have received a new nature, a divine nature and have been transformed from pigs and dogs into sheep. (2 Peter 1:4) The change is more than just cosmetic, as in 2 Peter 2:20. These cleaned up on the outside dogs and pigs were never sheep.
*Compare 2 Peter 1:4 -
"partakers of the divine nature, having escaped the corruption - Strongs #5356 that is in the world through lust with 2 Peter 2:20 - with they
escaped the pollutions - Strongs #3356 (different Greek word) of the world through the knowledge of the Lord and Saviour Jesus Christ, yet they are again entangled therein, and overcome. *Notice that 2 Peter 2:20
did not mention them being "partakers of the divine nature."
Corruption (Strongs #5356) (to shrivel or wither, spoil, ruin, deprave, corrupt, defile, to destroy by means of corrupting, to spoil as does milk). Corruption - describes decomposition or rotting of an organism and the accompanying stench. The utter depravity of the fallen flesh and the resultant moral decomposition of the world opposed to God is driven by it sinful lusts or evil desires.
Internal corruption.
Pollutions/Defilements (Strongs #3393) ("pollutions", "filthy things", "contaminations", "world's filth") describes the state of being tainted or stained by evil and refers to impurity, impure, tainted, defilement, foulness or pollution.
Pollutions/Defilement refers to what is on the
outside (2 Peter 2:20). But genuine believers have escaped the corruption that is in the world through lust (2 Peter 1:4).
Corruption is deeper than pollutions/defilements on the outside: it is decay on the inside.
Having the knowledge of Jesus Christ does not save a person if there is
no heart submission to that knowledge. The latter end is worse than the beginning for these men because rejecting this knowledge will make them more accountable at the judgment.
1 Timothy 4:1 - Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
1 Timothy 4:1 - Now the Spirit expressly says that in latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons, 2 speaking lies in hypocrisy, having their own conscience seared with a hot iron, 3
forbidding to marry, and commanding to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth.
The words "the faith" (Greek tês pisteôs) in this context means
the apostolic faith, the New Testament apostolic body of doctrines. Some who are
in a state of professing adherence to the apostolic faith, nevertheless will in both doctrine and practice depart from it, giving heed to deceiving spirits and doctrines of demons. Some "nominal" Christians will abandon the Christian faith, the New Testament apostolic body of doctrines for cults or false religions. That does not prove they were previously born again. In 1 John 2:19, we read - They
went out from us, but they
were not of us; for
if they had been of us, they would have continued with us; but they went out that they might be made manifest, that
none of them were of us.
I believe the beginning of such a major departing from the apostolic faith was evidenced by the Roman Catholic church in the early 4th century. The Roman Catholic church
forbids its clergy to marry. This same church has other doctrines of demons such as transubstantiation, purgatory, indulgences, papal infallibility, Mary's perpetual virginity etc..
2 Thessalonians 2:3 - Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
Those who "permanently" fall away demonstrate that their faith was never firmly rooted and established from the start. 1 John 2:19 -
They went out from us, but they were not of us; for
if they had been of us, they would have continued with us; but they
went out that they might be
made manifest, that none of them were of us.
Hebrews 3:12 - Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.
Hebrews 3:14 - For we
have become [past tense Greek verb, gegonamen, meaning we have become already] partakers of Christ, if we hold fast the beginning of our confidence steadfast to the end. Notice that this is essentially a repeat of verse 6, where we have read: but Christ was faithful as a Son over His house -
whose house we are, if we hold fast our confidence and the boast of our hope firm until the end. The wording is not - "and you will become partakers of Christ (future indicative) if you (future indicative) hold fast." It is rather - "you have been, and now are, partakers of Christ,
(demonstrative evidence) if in the future you hold fast to Christ."
The point is that not all of these Hebrews have become partakers in their promised Messiah and of course, the only ones in the end who will be identified as truly born-again Hebrews who have partaken in Messiah, will have been those who have held fast the beginning of their confidence steadfast to the end. What about those faltering Hebrews who depart from God begin with loud confidence and profession of loyalty. But later?
Future perseverance is proof of genuine conversion.
In Hebrews 4:1-2, we read - "For indeed the gospel was preached to US as well as to THEM; but the word which THEY heard did not profit THEM,
not being mixed with faith in those who heard it. For
we who have believed do enter that rest, as He has said: "So I swore in My wrath, 'They shall not enter My rest," although the works were finished from the foundation of the world. Obviously, not all of these Hebrews were believers. Notice that verses 2-3 make a distinction between
US who have
BELIEVED and do enter that rest and
THEM who heard the word but
did not mix faith with what they heard and will not enter that rest because of
UNBELIEF.
