Then explain how John 5:24 doesn't say that believers possess eternal life and then explain how John 10:28 doesn't say that recipients of eternal life shall NEVER perish.
Every verse you think teaches loss of salvation is refuted by these 2 verses.
So I look forward to your 'explanations'.
I already did. Here it is again.
"Eternal Life refers to the Person of the Holy Spirit dwelling in you. Recall those verses in 1 Jn where it says no murderer has Eternal Life abiding in him, meaning the Holy Spirit abiding in him. The same Apostle says, that just as we have passed from death to life, by believing in Jesus Christ, we can pass from life to death by committing sins unto death like adultery, murder, apostasy etc. Recall that when David sinned by adultery/murder, he prayed:
"Cast me not away from Your presence; take not Your Holy Spirit from me." by which inspired words, the Holy Ghost Himself shows us that it is possible.
You have to understand the context of those 2 verses. In the first verse, the Lord is preaching the Gospel to unbelieving Jews. He tells them that not by keeping the law, etc, but rather by believing in Him, i.e. by faith, they can be justified.
The second verse is in a different context. The Lord sees the Pharisees are refusing to believe He is God. They want to prevent His disciples from believing that too. And so, He says, His Sheep will hear His Voice, that He knows them, and they follow Him. And to such as these He gives TWO GIFTS, not just one, the Holy Spirit, i.e. Justification, and the Gift of Never Perishing, i.e. Final Perseverance in Grace. It is those who receive these two gifts who are predestined not only to grace (justification) but also to final glory in Heaven (salvation). Also, your conflating the two is ultimately a non sequitur.
Take a secular example. Someone gives to group A a flight ticket as a gift. And to group B both a flight ticket and a first class ticket. Thus it therefore follow that all who have a flight ticket also fly first class? No, not at all. Likewise, it doesn't follow that all who receive eternal life (the Holy Spirit, by Grace through Faith, in Justification) also never perish. They alone never perish who do those 3 things mentioned by the Lord there. 2 Pet 1:5-11 confirms that when it says those who do things like e.g. add love, virtue, self-control etc to faith will never stumble, and in this way will confirm their election."
Again, all you have to do is read, Heb 10 in full, especially:
"39 But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul." to know that this still happens in the NT. In fact, the writer says that if, after being sanctified by the Blood of Christ, we return to death, that is worse than in the OT, and deserves greater punishment:
"29 Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?" So if even in the OT Kings like David, Saul and Solomon lost the Holy Spirit when they sinned gravely, it follows that the same is possible today. The same conclusion follows from 2 Pet 2:20-22 where it says apostates are worse than those who have never known Christ. But those who have never known Christ are lost. Hence, also it follows that apostates are also lost, and in addition will receive greater punishment in hell than those who never Christ, unless they repent of their apostasy before death, and have this sin too washed away in the Blood of Jesus, as per 1 Jn 1:8-10.
I would suggest reading the Church Father's commentary on the Scriptures. John Calvin said he got his OSAS opinion from St. Augustine - allegedly that Salvation = Justification. But St. Augustine didn't teach that. He taught: Justification + Perseverance = Salvation, as does the whole Holy Bible, both Old and New Testaments, Lord Jesus, Peter, Paul, James, John etc.
Chapter 9.— When Perseverance is Granted to a Person, He Cannot But Persevere.
Now, moreover, when the
saints say, Lead us not into
temptation, but deliver us from
evil,
Matthew 6:13 what do they
pray for but that they may persevere in
holiness? For, assuredly, when that gift of God is granted to them — which is sufficiently plainly shown to be God's gift, since it is asked of Him — that gift of
God, then, being granted to them that they may not be led into
temptation, none of the
saints fails to keep his perseverance in
holiness even to the end. For there is not any one who ceases to persevere in the
Christian purpose unless he is first of all led into
temptation. If, therefore, it be granted to him according to his
prayer that he may not be led, certainly by the gift of God he persists in that sanctification which by the gift of God he has received [and therefore receives final salvation/goes to Heaven, by dying having the Holy Spirit].
