You’re trying to make “the sheep” a fixed historical group who were already alive before the Gospel, but Jesus defines His sheep as those who hear His voice (John 10:27), not those who possessed prior covenant life.
Actually, He defines it by more than just that. Consider some more context that I believe is very relevant in defining what is being spoken about here in John. Those who are known by Jesus and the Father are those who already love Him (1 Corinthians 8:3).
John 10: 14-16 I am the good shepherd; and
I know My sheep, and am known by My own. As the Father knows Me, even so I know the Father; and I lay down My life for the sheep.
And other sheep I have which are not of this fold (Gentiles); them also I must bring,
and they will hear My voice; and there will be one flock (The body of Christ, the baptism with the Holy Spirit) and one shepherd.
John 10:26-29 But you do not believe, because you are not of My sheep, as I said to you.
My sheep hear My voice, and I know them, and they follow Me.
And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand.
My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of My Father's hand.
Romans 8:28-30 And we know that all things work together for good to those who love God, to those who are the called according to His purpose.
For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren.
Moreover whom He predestined, these He also called; whom He called, these He also justified; and whom He justified, these He also glorified.
1 Corinthians 8:3 But if anyone loves God, this one is known by Him.
The sheep are those whom He knows, and know Him, and that's who hears His voice.
Those who hear His voice are those that the Father gave Him. Not only from Israel, the Jews that were His audience at that time, but also those OT believers from other nations. Like the disciples of John the Baptist in Acts 19, who already loved God and were declared righteous in promise by faith. They were known by God because they already loved Him. These were given to the Son, but had not yet heard the Gospel and received the promises, mainly eternal life. These were not atheists, these were OT believers baptized in John baptism, publicly identifying with his teaching of the coming Messiah. They loved God and were know by Him already. Predestined to hear the Gospel (His sheep), and believe, and receive the life, the indwelling Holy Spirit that places a believer in Christ, where all the ingredients that save them are now available in Christ. Like Cornelius, a man who feared God, thus he loved God and was known by Him. An OT believer, predestined to be in Christ and have the life that conforms him to Christlikeness. Lydia too, she worshipped God, God already knew her because she loved Him, but did not yet know Jesus and the Gospel. All they had was only in promise until God opened her heart to believe, why? Because she was predestined as an OT believer who loved God. These are the ones that the Father gave to the Son, the Sheep, who hear Jesus. (BTW, the OT Jews who Jesus said were of the devil and would not believe in John 10, they were not His sheep, meaning they were not genuine OT believers given to him by the Father. If they were, they would have heard and believed.) like the OT believers at Pentecost, the three thousand. All those countries listed, represented by OT believers, mostly proselyte Jews, true OT believers that came to celebrate Pentecost, and hearing the Gospel they believed the Gospel as Jesus said they would, and taking that indwelling back to all those other nations, the presence of God, fulfill Jesus' prophesy that when He is lifted up glorified, He will draw all nation to Himself (John 12:32). Thew whole book of Acts is OT believes, already declared righteous by faith, already owed the promise of salvation, they just needed it to be realized, thus Christ needed to be lifted up, ascend, glorified, sitting at the right hand of the Father, then all those who this promise was owed to, obtaining that only in Christ, the Holy Spirit is given, placing them in Christ so that they can receive all those saving ingredients.
Dave, your entire argument depends on turning πίστιν (faith) in 2 Peter 1:1 into “spiritual life,” but Peter never does that; he explicitly says the thing obtained is faith, and then immediately commands believers to add to your faith virtue, knowledge, self‑control, perseverance, godliness, brotherly kindness, and love — which is impossible if faith is the spiritual life itself. You’re trying to make “our Savior” mean “He was already legally their Savior before they obtained faith,” but the possessive pronoun is covenantal, not chronological; Peter is writing as a believer to believers, not describing their pre‑faith legal status. Your Hebrews 12:2 move is a category mistake: the author uses faith as the path Christ pioneers, not as a metaphor for regeneration, and Peter’s own context distinguishes life and godliness (v.3) from faith (v.1). When you say “salvation happens first as a sovereign act of God, and faith is the immediate result,” you’re reversing the NT order: justification is through faith (Rom 5:1; Gal 2:16), not before it, and regeneration is the cause of faith, not the verdict of salvation. Your “initial faith vs. later faith” distinction is an invented patch to preserve your system, not something Peter ever articulates; he treats faith as the instrument by which believers enter the life he describes, not the life itself. The grammar is fatal to your reading: Peter says faith was obtained, not life was obtained, and your argument only works if you rewrite the text to say the opposite.
I fixed your quote, you addressed Roger, not me.
Peter is speaking to believers, I agree, and that was my point. These believers would have already obtained the life from first believing. Peter is admonishing them to build that faith/life, not just sit idly and do nothing. Just like James, a faith should be active, growing, not idol. They had the life from believing, now they needed to grow in it. He's speaking of the life, called faith, just like Scripture often does. This must be distinguished from the initial believing, which does not have the life, but is the reason that we receive that life. The distinction is made here...
Galatians 2:20 I have been crucified with Christ; (This happens in Christ, Romans 6:3-11) it is no longer I who live, but Christ lives in me;
and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me.
And separates the initial believing with that life/faith.
John 20:31 but these are written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His name.
Isn't that what the Gospel message is, believe and be saved?
To apply the initial believing to what Peter was saying goes beyond the text. Peter was speaking of the life, called faith. Todays reformed believers always use passages speaking of one or the other specifically, and use those passages to apply to both, but that's why their theology is a mess. A distinction needs to be made between our initially believing to obtain the life, and the life, called faith, that we receive as a result of believing, to accurately define Scripture.
As I stated already, we have access to the grace/life/faith by faith (Romans 5:1-2).
I believe that Peter is speaking of the life, that comes as a result of believing. Look at it again...
2 Peter 1:1
Simon Peter, a bondservant and apostle of Jesus Christ, To those who have obtained like precious faith with us by the righteousness of our God and Savior Jesus Christ:
It's just another example of which there are many, where people are trained to read things into a verse, assuming that the same thing is taught everywhere in the Bible. But "everywhere" is a whole bunch of verses that people are reading things into. When we look for the clear passages that aren't read into, we cannot find them. That's Calvinism in a nut shell, the TULIP system has become the context that the Bible is interpreted from. Like with the sheep, it's there, the definition, but what is read into that passage from TULIP takes the defining seat, not the actual Biblical context.
I consider myself reformed, but not Catholic light reformed. I'm going to invent a new theological camp. I call it 'more reformed than you'. lol
Compare Hebrews 12:2 with Acts 3:15
