It is so important to take all scripture in "context"..or we can "make" it say what we want. I encourage people to read scripture in context when a scripture by itself is being presented without the context it was written in and taking the clear known scriptures to compare it with.. All scripture must be compared with other scripture.
Never let an obscure scripture rob you of the truth of the very clear scriptures. If the obscure scriptures seems to contradict known clear ones - then we are reading it wrong and we need to rely on the Holy Spirit for proper understanding of it.
The whole chapter 2 in 2 Peter is talking about false prophets in verse 1...then in verse 9 Peter talks about the unrighteous ( the unbeliever )..then in verse 13..they are stains and blemishes ( believers have no spot or blemish because of Jesus..1 Peter 1:19 Eph 5:27 Eph 1:4 )..all through that chapter he is not describing a believer in Christ.
Here is an excellent response about 2 Peter 2:20 from mailmandan:
Quote:
2 Peter 2:20 - Those who are truly born of God 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. *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.
