“The truth of eternal security is inherent in the nature of salvation itself.” Lewis Sperry Chafer
Eternal security is the present possession of eternal life. In other words, from the point of salvation, it is the irrevocable and unfailing condition of eternal life guaranteed the true believer in Christ.
If salvation can be lost, it is vital that Christians not be given a false sense of security. If salvation is secure, it is vital that Christians not anguish over a nonexistent possibility.
If salvation is truly by grace, I think there can be only one possible resolution to the issue. Because of God's grace we are eternally secure.
Acts 15:11
But we believe that we are saved through the grace (the undeserved favor and mercy) of the Lord Jesus, just as they [are].
When does grace stop being grace after we are saved? Does that mean after we are saved it's no longer grace but works? So we are saved by grace but kept by works.
Romans 3:24
[All] are justified and made upright and in right standing with God, freely and gratuitously by His grace (His unmerited favor and mercy), through the redemption which is [provided] in Christ Jesus,
Romans 4:6
Therefore, [inheriting] the promise is the outcome of faith and depends [entirely] on faith, in order that it might be given as an act of grace (unmerited favor), to make it stable and valid and guaranteed to all his descendants—not only to the devotees and adherents of the Law, but also to those who share the faith of Abraham, who is [thus] the father of us all.
Romans 11:5–6
So too at the present time there is a remnant (a small believing minority), selected (chosen) by grace (by God’s unmerited favor and graciousness).
6 But if it is by grace (His unmerited favor and graciousness), it is no longer conditioned on works or anything men have done. Otherwise, grace would no longer be grace [it would be meaningless].
Galatians 2:21
[Therefore, I do not treat God’s gracious gift as something of minor importance and defeat its very purpose]; I do not set aside and invalidate and frustrate and nullify the grace (unmerited favor) of God. For if justification (righteousness, acquittal from guilt) comes through [observing the ritual of] the Law, then Christ (the Messiah) died groundlessly and to no purpose and in vain. [His death was then wholly superfluous.]
Ephesians 2:5–6
Even when we were dead (slain) by [our own] shortcomings and trespasses, He made us alive together in fellowship and in union with Christ; [He gave us the very life of Christ Himself, the same new life with which He quickened Him, for] it is by grace (His favor and mercy which you did not deserve) that you are saved (delivered from judgment and made partakers of Christ’s salvation).
6 And He raised us up together with Him and made us sit down together [giving us joint seating with Him] in the heavenly sphere [by virtue of our being] in Christ Jesus (the Messiah, the Anointed One).
Astonishing as it may sound, Christians are united with Jesus Christ in His resurrected life. Physically, we still live in the natural world. But God, by His great power, and because of His immense love, mercy, and grace, raised us from our spiritually dead status to new life in Christ. We now sit in heavenly places. God's going to make sure we don't lose our position. We are eternally secure.
2 Timothy 1:9–10
[For it is He] Who delivered and saved us and called us with a calling in itself holy and leading to holiness [to a life of consecration, a vocation of holiness]; [He did it] not because of anything of merit that we have done, but because of and to further His own purpose and grace (unmerited favor) which was given us in Christ Jesus before the world began [eternal ages ago].
[It is that purpose and grace] which He now has made known and has fully disclosed and made real [to us] through the appearing of our Savior Christ Jesus, Who annulled death and made it of no effect and brought life and immortality (immunity from eternal death) to light through the Gospel.
Hebrews 6:13-20
13 For when God made [His] promise to Abraham, He swore by Himself, since He had no one greater by whom to swear,
14 Saying, Blessing I certainly will bless you and multiplying I will multiply you.
15 And so it was that he [Abraham], having waited long and endured patiently, realized and obtained [in the birth of Isaac as a pledge of what was to come] what God had promised him.
16 Men indeed swear by a greater [than themselves], and with them in all disputes the oath taken for confirmation is final [ending strife].
17 Accordingly God also, in His desire to show more convincingly and beyond doubt to those who were to inherit the promise the unchangeableness of His purpose and plan, intervened (mediated) with an oath.
18 This was so that, by two unchangeable things [His promise and His oath] in which it is impossible for God ever to prove false or deceive us, we who have fled [to Him] for refuge might have mighty indwelling strength and strong encouragement to grasp and hold fast the hope appointed for us and set before [us].
19 [Now] we have this [hope] as a sure and steadfast anchor of the soul [it cannot slip and it cannot break down under whoever steps out upon it—a hope] that reaches farther and enters into [the very certainty of the Presence] within the veil,
20 Where Jesus has entered in for us [in advance], a Forerunner having become a High Priest forever after the order (with the rank) of Melchizedek.
1 Peter 1:3-6
Praised (honored, blessed) be the God and Father of our Lord Jesus Christ (the Messiah)! By His boundless mercy we have been born again to an ever-living hope through the resurrection of Jesus Christ from the dead,
4 [Born anew] into an inheritance which is beyond the reach of change and decay [imperishable], unsullied and unfading, reserved in heaven for you,
5 Who are being guarded (garrisoned) by God’s power through [your] faith [till you fully inherit that final] salvation that is ready to be revealed [for you] in the last time.
6 [You should] be exceedingly glad on this account, though now for a little while you may be distressed by trials and suffer temptations,
1 John 2:25
And this is what He Himself has promised us—the life, the eternal [life].
If he would take away that promise of eternal life it wouldn't be eternal. And it wouldn't be a promise he makes sure that doesn't happen.
But not to worry because we have eternal security.
1 John 5:9–13
If we accept [as we do] the testimony of men [if we are willing to take human authority], the testimony of God is greater (of stronger authority), for this is the testimony of God, even the witness which He has borne regarding His Son.
10 He who believes in the Son of God [who adheres to, trusts in, and relies on Him] has the testimony [possesses this divine attestation] within himself. He who does not believe God [in this way] has made Him out to be and represented Him as a liar, because he has not believed (put his faith in, adhered to, and relied on) the evidence (the testimony) that God has borne regarding His Son.
11 And this is that testimony (that evidence): God gave us eternal life, and this life is in His Son.
12 He who possesses the Son has that life; he who does not possess the Son of God does not have that life.
13 I write this to you who believe in (adhere to, trust in, and rely on) the name of the Son of God [in the peculiar services and blessings conferred by Him on men], so that you may know [with settled and absolute knowledge] that you [already] have life, yes, eternal life.
If you could lose your salvation then it never was eternal life but that's not what the Bible teaches...the Bible teaches we are eternally secure
