Salvation is truly the work of God and not a matter of our own work, although with salvation obedience with our work will show it, And God gives eternal life according to his knowing everything and he is never mistaken. Saying that we are once saved always saved as long as our faith remains in Christ is combining passages for it in a synthesis, which must only be done with great care to preserve truth that is taught. We are indeed saved according to our faith, that is from scriptural passages, it is the work of Yahweh God and it is his grace, that is from scriptural passages, but there is not suggestion that it is those with saving faith that would turn from the faith, that is only read into the scriptures.
How can one lose something he never possessed? I really think many seek God to satisfy their own hearts desire. I believe with all of my heart these have no clue that's what their doing... (Food for thought)
^Example^ A church can be found on every street corner God's appointed cannot.
I am not sure what you are saying. I can say these things, if it is about the reference in Hebrews 6 about those who were once enlightened, and have tasted the heavenly gift, and have become partakers of the Holy Spirit, and have tasted the good word of God and the powers of the age to come, it is not saying of them that they actually came to faith. Better understanding of this is with seeing the whole context around that reference:
First, the inspired writer writes "leaving the discussion of the elementary
principles of Christ, let us go on to perfection, not laying again the foundation of repentance from dead works and of faith toward God, of the doctrine of baptisms, of laying on of hands, of resurrection of the dead, and of eternal judgment." There are the more mature things to pursue to be written for believers, these elementary things are basic for those just coming to Christ. Those once enlightened, then, may come to having these revealed to them. No coming to the essential faith necessarily there. Remember the Holy Spirit came upon certain individuals named in the old testament, we cannot honestly say every one of them was saved. The Spirit of God comes to reveal things to individuals before they come to salvation in Christ, but not every one comes to Christ from that, many are resistant, and may just passively look into it.
Right after speaking about those of verses 4, 5, and 6, the inspired writer wrote " But, beloved, we are confident of better things concerning you, yes, things that accompany salvation, though we speak in this manner. For God
is not unjust to forget your work and labor of love which you have shown toward His name,
in that you have ministered to the saints, and do minister. And we desire that each one of you show the same diligence to the full assurance of hope until the end, that you do not become sluggish, but imitate those who through faith and patience inherit the promises." The believers are addressed directly as distinct from any who might associate with them who would depart from trusting Christ, the context of the book showing such at that time to be those, being already Jewish, trusting their works in the Law in preference to the work of Christ in which there is salvation according to faith in Christ through the grace of God.
I apologize if this addresses what you did not mean, but it may answer others who do not understand this.
Concerning the rest posted that was not fully clear to me, I can say this which might relate to that, those who are not true believers in Christ, whether they profess to be or are against it, are generally seeking on some level. There is an emptiness present, and it is filled with coming to Yahweh God in relationship made available through Christ. Many try filling the emptiness with other things. I believe God is gracious to those who honestly seek him, up to when they might come to Christ when the revelation for that comes to them, graciousness may be removed when any harden themselves to that at that point. There are indeed many churches and there would be some of them anyway having few who truly follow Christ among them.
