Maybe this is just semantics (maybe we agree but just speak differently) because I don't see how the parable of the sower proves that the people Peter is talking about were never saved.
If those people are like the seed that fell on thorny ground...well...that seed actually became a plant with roots. True, it was eventually choked out by the thorns (ie. the pollution of the world) but we don't say that it was never a plant. It surely was.
Let's look at the
CONTEXT of Christ's infallible interpretation of the 'types of ground' and the results of seed (the Word/Gospel) falling on them:
Matthew 13:20-23 (ASV) And he that was sown upon the rocky places, this is he that heareth the word, and straightway with joy receiveth it; yet hath he not root in himself, but endureth for a while; and when tribulation or persecution ariseth because of the word, straightway he stumbleth. And he that was sown among the thorns, this is he that heareth the word; and the care of the world, and the deceitfulness of riches, choke the word, and he becometh unfruitful. And he that was sown upon the good ground, this is he that heareth the word, and understandeth it; who verily beareth fruit, and bringeth forth, some a hundredfold, some sixty, some thirty.
Okay.... so here we have first type of ground we want to consider (the second type of ground, the first being where there was initially no understanding), i.e., the
rocky ground. The seed doesn't penetrate the soil and thus there is no germination, no root is formed. Thus there is the
appearance of growth, but it not a spiritual plant. We might classify this
appearance as a weed, undesirable and incapable of producing any acceptable fruit. This 'weed' eventually dies because of its superficiality; no root. It cannot withstand the pressures (tribulation/persecution) of the world, that comes against those who profess faith. In short, there is no real spiritual life, no commitment to Christ which demands that one pick up his cross and follow Him.
The second (third) type of ground is the
thorny ground. Here the individual 'hears the word' (externally with the ears) but there is again no real spiritual life, no commitment to following Christ, but in this case the allurements of this world and its philosophy has precedence. The result is this person abandons what he/she professed thus showing that they were never genuinely regenerated and converted.
The last type of ground is called "good", i.e., it is fertile and it allows that which was heard in the Gospel to take root resulting in a genuine change, aka: repentance and a growth in spirituality... sanctification.
Thus, I am suggesting that those individuals referenced by Peter are examples of those represented by the rocky and thorny individuals in the parable of the Sower. Again, I would recommend you read the entire chapter (2Pet 2) and carefully consider how he describes these individuals which is totally pejorative.
Likewise, when Peter is talking about people who "escaped the pollution of the world" it seems that we shouldn't speak as if they had never escaped the pollution of the world. They had. Peter said so. And when people escape the pollution of the world, we call them "saved." Right?
I am NOT denying the description of "having escaped the pollution of the world", but rather interpreting it differently than you do. I am assuming that you are wanting to understand the word "escape" as salvific. And I am saying that it is not salvific but rather a perception. These individuals made a profession and perhaps initially abstained from certain perceptible sins. But it was 1) superficial, e.g., the 'righteousness' of the Pharisees, and 2) quickly abandoned and these people's lives became even worse than what it was before they made a profession to be a follower of Christ.
You and others here have escaped the pollutions of the world, I would assume, and as a result call yourselves "saved."
Yes, this is certainly true. And what is also true is that there are those who are 'religious' outwardly, but inwardly they are yet dead in sin. Counterfeits look very much like the real thing, don't they? Even the Devil himself can transform himself to
appear as an "angel of light" (2Cor 11:14). But, I seriously doubt you would say Satan was once saved and then lost that salvation, right? There are many false professors, false gospels, false spirits, false prophets, false teachers, etc., who outwardly have the
appearance of being genuine.
