(From previous post)
"My sheep hear my voice, and I know them, and they follow me; and I give them eternal life, and they shall never perish, and no one shall snatch them out of my hand." (John 10:27-28) Jesus is again juxtaposing the giving of eternal life (salvation) with perishing (being condemned).
"And this is eternal life, that they know thee the only true God, and Jesus Christ whom thou hast sent." (John 17:3) I guess this is
the definition of eternal life, eh?

Knowing God is something we accomplish when we are face to face with Him; we know the Father through the Son, but we will know God in His Completeness when we see Him.
And when the Gentiles heard this, they were glad and glorified the word of God; and as many as were ordained to eternal life believed. (Acts 13:48) To “ordain” means “to dictate, to decree; to pre-arrange; to establish”. I think this fits in with the “inheritance” economy.
But by your hard and impenitent heart you are storing up wrath for yourself on the day of wrath when God’s righteous judgment will be revealed. For he will render to every man according to his works: to those who by patience in well-doing seek for glory and honor and immortality, he will give eternal life; but for those who are factious and do not obey the truth, but obey wickedness, there will be wrath and fury. (Rom 2:5-8) On the day of judgment, God gives eternal life to the righteous.
But then what return did you get from the things of which you are now ashamed? The end of those things is death. But now that you have been set free from sin and have become slaves of God, the return you get is sanctification and its end, eternal life. (Rom 6:21-22) Upon submitting ourselves to the will of God, we begin the process of sanctification, the end of which is eternal life.
For he who sows to his own flesh will from the flesh reap corruption; but he who sows to the Spirit will from the Spirit reap eternal life. (Gal 6:8) Eternal life is the “crop”, a life in the Spirit is the “seed”.
Fight the good fight of the faith; take hold of the eternal life to which you were called when you made the good confession in the presence of many witnesses. (1 Tim 6:12) I think Paul is challenging them to live their lives as though they have already received what was promised to them, or else he’s using emphasis to say “wake up and live like a Christian!”
Paul, a servant of God and an apostle of Jesus Christ, to further the faith of God’s elect and their knowledge of the truth which accords with godliness, in hope of eternal life which God, who never lies, promised ages ago. (Tit 1:2) We are in the hope of eternal life, which is a promise from God.
So that we might be justified by his grace and become heirs in hope of eternal life. (Tit 3:7) We are heirs to eternal life (our inheritance).
And this is what he has promised us, eternal life. (1 John 2:25) It is a promise to be realized.
Any one who hates his brother is a murderer, and you know that no murderer has eternal life abiding in him. (1 John 3:15) This is tricky. I think it means that eternal life is a
part of us, so long as we are in Christ. That is, eternal life is due to the dwelling of the Spirit of God in us, and so no one without the Spirit of God dwelling in him (such as an unrepentant murderer) has eternal life within him.
And this is the testimony, that God gave us eternal life, and this life is in his Son. He who has the Son has life; he who has not the Son of God has not life. I write this to you who believe in the name of the Son of God, that you may know that you have eternal life. (1 John 3:11-13) This (which you quoted) is also kind of tricky to reconcile with the previous Scriptures. I think the key is that John says “this life is in his Son”, so eternal life isn’t “had” as a possession is had, it’s “had” in the sense that we abide in it (as it abides in us) when we are in Christ. I’m open to other interpretations, so long as they don’t end up contradicting the previous passages.
But you, beloved, build yourselves up on your most holy faith; pray in the Holy Spirit; keep yourselves in the love of God; wait for the mercy of our Lord Jesus Christ unto eternal life. (Jude 20-21) I think this speaks towards the inheritance of eternal life as the “final act of mercy”, if you will, of Jesus Christ to us who remain in him.
