Perseverance of the saints is the teaching that the work of God the Holy Spirit will never cease in the Christian, and all who are truly regenerated will never stop believing and trusting in Christ, and they will never lose their salvation, and they will persevere to the end because God has promised to never leave them or forsake them.
The doctrine of perseverance is based in the doctrines of
election and
predestination where God elects (chooses) people for salvation (
2 Thessalonians 2:14) and predestines (brings about by
His sovereign will in regards to salvation, Ephesians 1:3-4, 11,
Romans 8:29) the redemption of those elect and
justifies them (declaring them legally righteous,
Romans 4:5, Romans 5:1) by grace alone
in Christ alone apart from the works of the Law (
Romans 3:28,
Romans 4:5). If God is sovereign and He works all things after the council of His will (
Ephesians 1:11), then He sovereignly keeps all whom He has redeemed.
“They whom God hath accepted in his Beloved, effectually called and sanctified by his Spirit, can neither totally nor finally fall away from the state of grace; but shall certainly persevere therein to the end, and be eternally saved”.
The whole relation between the believer and his God is one of eternal sonship, which cannot be broken; hence all judgments of God upon His own are for correction. “He that believeth on him [in Christ] is not condemned”.
To challenge the eternal security of the believer is to deny that the prayer of the Son of God will be answered and to deny the eternal efficacy of His atoning blood. In ignorance, perhaps, such insult has been heaped upon the blessed Savior; yet still He is faithful. He prays and
appears before the Father in behalf of just such ignorant or sinning believers.
Sonship is eternal. It is the result of a birth which secures the impartation of a new divine nature. It is impossible to remove from a child the nature of his human father. It is a deeper and more abiding reality to have partaken of the divine nature. The
born-again one thus possesses “eternal life” by a legitimate birth, and can “never perish.” It could not be eternal life that is imparted with no possibility of perishing and then be lost by no greater force than the feeble act of man, that act moreover already having been covered with atoning blood.
A serious theological problem would arise if Spirit baptism could be repeated. A believer would somehow have to be removed from the body of Christ in order to be baptized into it again. And, of course, regeneration or the impartation of spiritual life by the Holy Spirit and His subsequent permanent
indwelling would preclude any thought of losing one’s salvation or of forfeiting the Spirit’s residence within the believer.
There are verses about continuing in the faith. Those with “true” faith will not fall away. The purpose of these verses is always to warn those who are thinking of falling away or have fallen away that it is a strong indication that they were never saved in the first place (
1 John 2:19).
Colossians 1:23 [And this He will do]
provided that you continue to stay with and in the faith [in Christ], well-grounded and settled
and steadfast, not shifting
or moving away from the hope [which rests on and is inspired by] the glad tidings (the Gospel), which you heard and which has been preached [as being designed for and offered without restrictions] to every person under heaven
Hebrews 3:14 For we have become partakes of Christ, if we hold fast the beginning of our assurance firm to the end
1 Peter 1:5 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.
To the topic NOT BY WORKS ...
To believe that the source of salvific faith is the individual via 'free will' and not the work of the Spirit is to make faith a work. A work in the dictionary is defined "as a mental or physical process to achieve a goa"l. According to many "free willers", they must continue through their own power of "free will" to believe or lose their salvation. This is a continuation of WORK SALVATION ... the continuing of doing something in order to be save, continuing to believe of their own power. This calls for righteousness (works) on their part which contradicts scripture.
.... The bible states that we are Ephesians 2:8 For by grace you have been
saved through faith. And this [referring to salvation through faith]
is not your own doing; it is the gift of God, 9 not a result of works (not founded upon anything in the believer himself), so that
no one may boast. God gives us the gift of faith so none may boost.
Aside: Admittedly, our Arminian brothers do not claim their faith which is dependent on themselves to be a work as they are aware we are not saved by works ... it is a contradiction they deny.
