Sheep make it, but dogs and pigs don't make it.
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 - 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 true 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. True believers have received a new nature, a divine nature, and they have new and different appetites and desires. They have been transformed from pigs and dogs into sheep. The change is more than just cosmetic, as in 2 Peter 2:20.
Having the knowledge of Jesus Christ, even the more intimate knowledge of "epignosis," does not save a person if there is no heart submission to that knowledge. For epignosis to be of any spiritual value, there must be a heart submission to that knowledge. A person who rejects this knowledge will be more accountable at the judgment. Peter did not mention that those who escaped the "pollutions of the world" through the knowledge of the Lord and Savior Jesus Christ, were "partakers of the divine nature," "born again" or "saved."
