The Holy Spirit does more than merely "seal" us, of course. He also "washes" us and regenerates us spiritually (Titus 3:5). He is the Source of the believer's spiritual life (Romans 8: 10-11), the means of the believer's second birth. He it is who transforms the believer, making the believer a "new creature in Christ" in whom "old things are passed away, behold, all things are become new." (2 Corinthians 5:17) ...
Certainly the Holy Spirit does more than seal us. I was replying to the claim that seal = ensure faith continues. The other things the Spirit does which you mention (washing/baptism, new birth/new life in Christ, etc. all follow faith - they do not precede it. (Gal 23:6-7, Rome 2:3-4, etc.)
John 10:28-29
28 And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand.
29 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.
Please check the Greek verbs of this verse, as most English translations opt for ease of reading over accurace. These verse, in the Greek, say
"I give (present, ongoing) them eternal life, and they shall not be destroyed unto the age (e.g. they shall not be destroyed utterly/forever), and nothing can seize (future) them from my hand. My Father, who gives (present, ongoing) them to me is greater than all, and so it is not possible for anyone to seize (present) them from the hand of my Father."
Nothing in the verses prevents them from willingly leaving the shepherd - it just shows no one (such as the 'wolves' Jesus mentioned) having the power to seize them from the Father. Eternal life is an ongoing gift of God culminating in a final eternal life at the judgement whereby they will not be destroyed. It's beyond the scope of the passage to claim it proves man cannot cease faith and reject the promises or eternal life that God gives.
1 Thessalonians 5:23-24
23 Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ.
24 He who calls you is faithful, who also will do it.
This is a blessing Paul prays for the believers, not a statement that they can't reject faith. He reminds them of the hope that Christ has the power to keep them - it is not a statement that they cannot leave the protection of that power by rejecting faith. Again, it is beyond the scope of this passage to interpret it as making commentary on whether someone will continue in faith or not.
Philippians 1:6
6 being confident of this very thing, that
He who has begun a good work in you will complete it until the day of Jesus Christ;
Faith is not part of the good work Jesus began in us. He began the good work because we responded to the gospel in faith (by God's gracious choice, not because faith merited it.) That good work includes the indwelling Spirit, the mind of Christ, being conformed to Christ, growing in Christ, etc. Jesus continues to give us nutrients to grow as we remain in Him, allowing us to bear fruit (II Pet 1:3-11, etc.) It is again beyond the scope of the passage to claim it mandates that we remain in Christ and continue in faith.
And so on. You see, our salvation is not us-contingent, but Christ-contingent. He is our salvation; we are not.
We are not our salvation, certainly. But our salvation is dependent on our faith in Christ's work to bring us salvation. Without faith, we cannot claim the promise of salvation. (I Pet 1:3-9, I Jn 2:27-28, I Cor 15:23) Salvation doesn't create faith, and faith does not create salvation. But our faith in Christ is the requirement by which God chooses to apply Christ's saving work to our account.
God brought salvation through Christ, not through man (
Heb 11:32-40,
Isaiah 63:5,
Titus 3:3-8). However, we do need faith to receive salvation (
I Pet 1:3-9,
John 3:14-17,
II Tim 2:10-13,
II Tim 3:10-17,
I John 2:24-25,
Rom 1:16-17,
Gal 3:7-14,
Rom 10:5-13). Faith is the persuasion that it is Christ who has the power to save us.
Hebrews 6:4-7
4 For it is impossible for those who were once enlightened, and have tasted the heavenly gift, and have become partakers of the Holy Spirit,
....
Does this verse demand the view that the "falling away" is from salvation? No. An unsaved "tare" may "fall away" from their proximity to the saving truth of the Gospel and participation in the life of the Church, and from a life that is, at least in its outward appearance, adhering to the teachings and example of Christ. Doing so puts the lost person well and truly beyond the pale. Having totally forsaken all association with the things of Christ and his Bride, such a person is fatally inoculated against repentance that leads to salvation.
I already went through this passage extensively in post #79 where I showed that the language (such as falling away and partaker) are extremely explicit in the Greek, as well as other evidences as to why the theory that they never really had faith fail.
And yes, the passage specifically demands that the falling away be from everything just described, including their former life-change due to partaking with the Spirit. There is no way to 'lessen' the force of the text to merely be about knowing about the Spirit or knowing people who had the spirit and seeing some miracles, etc. Furthermore, the term for fall away is explicit - not about mere proximity to but active participation and affiliation with before one's defection.
John 15:1-8 (NKJV)
1 "I am the true vine, and My Father is the vinedresser.
2 Every branch in Me that does not bear fruit He takes away; and every branch that bears fruit He prunes, that it may bear more fruit.
3 You are already clean because of the word which I have spoken to you.
4 Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me.
5 I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing.
6 If anyone does not abide in Me, he is cast out as a branch and is withered; and they gather them and throw them into the fire, and they are burned.
7 If you abide in Me, and My words abide in you, you will ask what you desire, and it shall be done for you.
8 By this My Father is glorified, that you bear much fruit; so you will be My disciples.
What is the main thrust of this passage? Fruitfulness as a consequence of abiding in Christ.
“Every branch that bears not fruit He takes away...”
“Every branch that bears fruit He prunes it that it may bring forth more fruit.”
“The branch cannot bear fruit of itself...”
“He who abides in me, and I in him, the same brings forth much fruit...”
“...bear much fruit.”
Why is the unfruitful branch “taken away” and “cast into the fire”? Is the branch being judged and punished? No. Consider the following Scripture concerning the unfruitful vine:
Ezekiel 15:1-5 (NKJV)
1 Then the word of the Lord came to me, saying:
2 "Son of man, how is the wood of the vine better than any other wood, the vine branch which is among the trees of the forest?
3 Is wood taken from it to make any object? Or can men make a peg from it to hang any vessel on?
4 Instead, it is thrown into the fire for fuel; the fire devours both ends of it, and its middle is burned. Is it useful for any work?
5 Indeed, when it was whole, no object could be made from it. How much less will it be useful for any work when the fire has devoured it, and it is burned?
It's interesting that you stopped there, without citing God's conclusion:
"Therefore this is what the Sovereign Lord says: As I have given the wood of the vine among the trees of the forest as fuel for the fire, so will I treat the people living in Jerusalem.
I will set my face against them. Although they have come out of the fire, the fire will yet consume them. And when I set my face against them, you will know that I am the Lord.
I will make the land desolate because they have been unfaithful, declares the Sovereign Lord.” Ezek 15:6-8
That certainly seems to support, not contradict, that the useless vines would be consumed, not redeemed.
John 15:1-6 is concerned with the means to spiritual fruitfulness, not with teaching a saved-and-lost doctrine. The branches cast into the fire picture
the utter spiritual uselessness of
unfruitful branches, not of salvation lost. A vine is only useful when it is fruitful. Likewise, a believer who is not abiding in Christ cannot be spiritually fruitful and is, consequently, useless. That is the teaching of this passage.
In the passage Jesus is clearly speaking of being cut *out of Him* and not mere uselessness. Nor can he merely be speaking of works being burnt up - it isn't useless fruit being burned, but branches/people that do not remain in Him.
"He removes every branch in me that bears no fruit, while every branch that does bear fruit he prunes so that it will be even more fruitful." Jn 15:2 That certainly sounds like no longer being in Christ, not merely being unproductive in Christ. In fact, it sounds a lot like the warning of Rom 11:20-22:
"Granted. But they were broken off because of unbelief, and
you stand by faith. Do not be arrogant, but tremble. For if God did not spare the natural branches, he will not spare you either. Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you,
provided that you continue in his kindness. Otherwise, you also will be cut off."
Jn 15:6 "
If you do not remain in me, you are like a branch that is thrown away and withers; such branches are picked up, thrown into the fire and burned. " The branch isn't just useless - it is thrown away. The term can also be translated as 'Cast outside' - which you might recognize from many verses such as Matt 22:13 and Matt 25:30 where people are cast outside into darkness where there is weeping and gnashing of teeth.
Heb 6:4-6, a passage which in context is of former Christians who fell away, not mere 'lack of fruit' continues in Heb 6:7-8 with ""Land that drinks in the rain often falling on it and that produces a crop useful to those for whom it is tended receives the blessing of God.
But land that produces thorns and thistles is worthless, and it's curse is imminent. In the end it will be burned." If the useless thorns and thistles were the real problem, why would it need clarified that the *land* will be cursed and burned? After other comments, Paul exhorts them in Heb 6:12 "We do not want you to become lazy, but to
imitate those who through faith and patience inherit what has been promised." The direct implication is that those people who fell away are not inheriting the promise, as they did not patiently hold to faith.
