Its a lot harder to convince a person OSAS is wrong if they got sin that needs to be kept alive. Like if a person is divorced, really bad habitual sin, or abusive bully, OSAS gives a license to sin, backslider and let it slide with sin.
This first passage sets the staged. It is addressed to us who have received the faith, have knowledge of Jesus Christ, and have escaped the world of corruption. Remember the assertion is only the saved can receive faith, know Jesus Christ, we are partakers of his divine nature
2 peter 1
1Simon Peter, a bond-servant and apostle of Jesus Christ,
To those who have received a faith of the same kind as ours, by the righteousness of our God and Savior, Jesus Christ:
2Grace and peace be multiplied to you
in the knowledge of God and of Jesus our Lord;
3seeing that His divine power has granted to us everything pertaining to life and godliness, through the true knowledge of Him who called us by His own glory and excellence.
4For by these He has granted to us His precious and magnificent promises, so that by them you may become partakers of
the divine nature,
having escaped the corruption that is in the world by lust.
5Now for this very reason also, applying all diligence, in your faith supply moral excellence, and in
your moral excellence, knowledge,
6and in
your knowledge, self-control, and in
your self-control, perseverance, and in
your perseverance, godliness,
7and in
your godliness, brotherly kindness, and in
your brotherly kindness, love.
8For if these
qualities are yours and are increasing, they render you neither useless nor unfruitful
in the true knowledge of our Lord Jesus Christ. 9For he who lacks these qualities is blind or short-sighted, having forgotten his purification from his former sins. 10Therefore, brethren, be all the more diligent to make certain about His calling and choosing you; for as long as you practice these things, you will never stumble;
11for in this way the entrance into the eternal kingdom of our Lord and Savior Jesus Christ will be abundantly supplied to you.
12Therefore, I will always be ready to remind you of these things, even though you
already know
them, and have been established in the truth which is present with
you. 13I consider it right, as long as I am in this
earthly dwelling, to stir you up by way of reminder,
14knowing that the laying aside of my
earthly dwelling is imminent, as also our Lord Jesus Christ has made clear to me.
15And I will also be diligent that at any time after my departure you will be able to call these things to mind.
There is a tiny cheap shot in this passage about "forgetting his purification".......but its not what I want to focus on.
What I want to focus on this being addressed to those have received the faith. Only God can give them the faith and they have it.
Only the saved come to a knowledge of righteousness, only they can do righteous because of Christ. Only they can escape the corruption. If your not saved then you have not escaped the corruption you are still in the corruption.
2 Peter 2
20For if, after they have escaped the defilements of the world by the knowledge of the Lord and Savior Jesus Christ, they are again entangled in them and are overcome, the last state has become worse for them than the first.
21For it would be better for them not to have known the way of righteousness, than having known it, to turn away from the holy commandment handed on to them.
22It has happened to them according to the true proverb, “A DOG RETURNS TO ITS OWN VOMIT,” and, “A sow, after washing,
returns to wallowing in the mire.”
Here is one who had escaped because of Jesus Christ, but they FELL. They are WORST NOW then BEFORE being saved.
Its so bad they would have been BETTER OFF not knowing the way of righteousness.
Someone who has no knowledge of Jesus unsaved, they go to hell. Since when is that BETTER OFF then having KNOWN the way of righteousness?
A pig AFTER WASHING, after being CLEANED from their sin, goes back in the mud.
Its no coincidence he's using the same language from chapter prior.
I bet you can't name one person who is better off NOT knowing the way of righteousness then having known it.
Why can't you name one person? Because this was directed at people who believe in OSAS.
Everyone would argue without Jesus and being saved, it is impossible to KNOW the way of righteousness.
And if you disagree..... well who is he talking about? Name one person.
