It seems this is trying to force v.28 be a promise ONLY for those who follow Him. But John 5:24 shows plainly that one who believes HAS eternal life. Following Him is a lifestyle, over time. Believing is in a point in time. From the MOMENT one believes, they HAVE, possess, receive eternal life. And the promise is that they will never perish.
In John 10:28, the promise is clear; one will never perish by receiving eternal life. Nothing about any kind of lifestyle.
Why would He need to do this? His statement is clear enough. On the basis of receiving eternal life, one will never perish.
If there were conditions beyond receiving eternal life in order to never perish, Jesus would have made that clear.
But as it stands, He made no such exception or condition, beyond receiving eternal life.
Those who receive eternal life will never perish. Simple, clear, and straight forward. This is as plain as it can get.
He never said this. What He said is that those He gives eternal life will never perish, which is eternal security.
Are there any verses that speak to this?
Description of His sheep. And He taught how one becomes one of His sheep, back in v.9 - I am the gate; whoever enters through me will be saved.They will come in and go out, and find pasture.
Do you agree that the metaphor about being "the gate" and "entering through Me" refers to placing one's faith in Christ for salvation?
See? Nothing about being "in Me". Though I don't disagree that all believers are in Him, per Eph 1:13.
Is this a suggestion of being a fruit inspector to determine one's salvation?
My security is based directly on the promises of Scripture, not on my fallen flesh.
Grieving and quenching th Spirit are rampant today. Just look at all the Barna surveys and we see that born again believers are acting pretty much like unbelievers.
I've seen very little emphasis in pulpits today on the dangers and warning about grieving/quenching the Spirit.
Yet, Paul commands us to be filled with the Spirit and walk by means of the Spirit. This isn't automatic.
If I was preaching I would definitely warn of grieving the Spirit.
Hebrews 10
26 For if we go on sinning deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins,
27 but a fearful expectation of judgment, and a fury of fire that will consume the adversaries.
28 Anyone who has set aside the law of Moses dies without mercy on the evidence of two or three witnesses.
29 How much worse punishment, do you think, will be deserved by the one who has spurned the Son of God, and has profaned the blood of the covenant by which he was sanctified, and has outraged the Spirit of grace?
30 For we know him who said, "Vengeance is mine; I will repay." And again, "The Lord will judge his people."
31 It is a fearful thing to fall into the hands of the living God.
I would especially note that it is not based on what you have done at a moment in time, but based on being in Christ, that you will not receive the punishment of the wicked.
I would tell them not to take refuge in their belief, in a time when they did something or said something, but rather take comfort in the Spirit who lives in them.
Funny thing is, most people today are trying to be convinced they have the Spirit in them. As if someone would not know that the very Spirit of God lives in them. False teachers are convincing them that the Spirit lives in them because they did something. Truth is, if the Spirit of God is in someone, then they will know it.
1 John 5
1 Everyone who believes that Jesus is the Christ has been born of God, and everyone who loves the Father loves whoever has been born of him.
2 By this we know that we love the children of God, when we love God and obey his commandments.
3 For this is the love of God, that we keep his commandments. And his commandments are not burdensome.
4 For everyone who has been born of God overcomes the world. And this is the victory that has overcome the world-our faith.
5 Who is it that overcomes the world except the one who believes that Jesus is the Son of God?
6 This is he who came by water and blood-Jesus Christ; not by the water only but by the water and the blood. And the Spirit is the one who testifies, because the Spirit is the truth.
7 For there are three that testify:
8 the Spirit and the water and the blood; and these three agree.
9 If we receive the testimony of men, the testimony of God is greater, for this is the testimony of God that he has borne concerning his Son.
10 Whoever believes in the Son of God has the testimony in himself. Whoever does not believe God has made him a liar, because he has not believed in the testimony that God has borne concerning his Son.
11 And this is the testimony, that God gave us eternal life, and this life is in his Son.
12 Whoever has the Son has life; whoever does not have the Son of God does not have life.
13 I write these things to you who believe in the name of the Son of God that you may know that you have eternal life.
If you have the Son you have life, without Him you do not have life.
If I were preaching, I would end with this - do you have the Son?
