So far I've agreed with you on all you've said.
But above you do say something which is incredibly misunderstood by those who believe in eternal security.
I also believe in eternal security for as long as you trust in Jesus for your salvation.
IOW, the same belief that saved you is going to keep you saved.
What if you stop believing and return to a life of sin? Are you still saved?
If faith saves us..
Ephesians 2:8
How could no longer having faith still keep us saved?
2 Timothy 2:13
"If we are faithless, He remains faithful, for He cannot deny HIMSELF".
What do you suppose it means that God remains faithful to Himself?
If God DOES remain faithful to Himself, He certainly must require faith for one to be saved.
He does NOT remain faithful to the unbeliever, He remains faithful to HIMSELF.
To what He did for us on the cross...to what He deems just...to HIMSELF and HIS requirements.
Again, I am not in the Calvinist nor Arminian camps. I'm simply going by what Jesus taught.
The redeemed in Christ have their identity in Christ as Children of God. John 1. We are one with him in the spirit. 1Corinthians 6. Which is why Paul said there is no more division even among tribes of people. We are all one in Christ. Son's and daughters of Christ through the salvation and our atonement that was predestined by The Father and sealed by His Holy Spirit. Galatians 3.
27 For all of you who were baptized into Christ have clothed yourselves with Christ. 28 There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus. 29 And if you belong to Christ, then you are Abraham’s seed and heirs according to the promise.
When we're told in those Revelation scriptures that our name is in the Book of Life and it will not be blotted out, the one that wrote those names is our sovereign God that predestined us according to his will to become one with Christ. Ephesians 1, and particularly verse 4,
"even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. "
Romans 8, and Matthew 22:14 "For many are called, but few are chosen.”
Which speaks to those who are in Christ and predestined, were chosen by The Father to become sons and daughters of Christ, God. And those who think to become Christian but are really not so.
Our sovereign infinitely knowledgeable God wrote our names in the Book of Life first. Before anything we knew about salvation God knew us by name. Sometimes people refer to the Book of Revelation chapter 3 and verse 5 in order to argue that names can be blotted out of the BoL. But that's not what it is saying. 5."He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels."
Those who's name are in the book are already predestined to overcome the world because they are sealed with the Holy Spirit to the day of Redemption.
The teachings out there that promote the false notion that we can have our names blotted out of the book are wrong. And in my opinion, committing a heinous blasphemy against God The Father who wrote those names down. Because the teaching, from whatever camp it may arrive, is insisting in that teaching that God is not omniscient. That every verse in scripture that pertains to His sovereignty and foreknowledge and omnipotence, which is key, omnipotence, is false. And that The Father that said he knew us before we were conceived, Isaiah 44 & 49, Psalm 71 Jeremiah 1, Galatians 1 and on and on, because our souls come from God, “Before I formed you in the womb I knew you” (Jeremiah 1:5), and that being possible because the human reproduction system is God's making, was wrong. And his foreknowledge and sovereignty in writing those names in His Book of Life, key there, His, were a mistake that he didn't see coming when he failed to foresee, since he foreknew but couldn't foresee? That some of those names would fail in his expectation of them.
That is worldly teaching that attempts to impart humans are able to overcome God's will for them.
