Let’s test that hypothesis.
First assumption is that one is a saint (Perseverance of the Saints does not apply to non-saints).
Second assumption is that a saint (one who is saved) will remain saved until the end (glorification).
So what does Scripture say:
[John 10:27-29 NASB] 27 "My sheep hear My voice, and I know them, and they follow Me; 28 and I give eternal life to them, and they will never perish; and no one will 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 the Father's hand.
- “my sheep follow me” indicates that the Saints (Jesus’ sheep) will and do follow him. It does not say SOME sheep, so it must imply that ALL of Jesus’ Sheep (the Saints) will and do follow him. It does not say MAY follow him, or speak of WANDERING OFF, so it is not unreasonable to conclude that ALL of Jesus‘ sheep WILL follow him and keep on following him.
- ”I give eternal life to them” makes the gift a permanent one since ETERNAL life is not ETERNAL if one later looses it.
- “They will never perish” repeats the message just in case you missed it the first time. NEVER perish means never, not until you do perish.
- “No one will snatch them out of my hand” is an assurance of perseverance. Is there any doubt that those in God’s hand are “Saints”?
- “no one is able to snatch [them] out of the Father's hand” So no one will and no one is able to. That is assurance of salvation. (PS. If someone ‘jumps’ out of their hands, then they WERE both able to and did ’snatch themselves’ out ... making the claim of Christ false.)
[Ephesians 1:9-11 NLT] 9 God has now revealed to us his mysterious plan regarding Christ, a plan to fulfill his own good pleasure. 10 And this is the plan: At the right time he will bring everything together under the authority of Christ--everything in heaven and on earth. 11 Furthermore, because we are united with Christ, we have received an inheritance from God, for he chose us in advance, and he makes everything work out according to his plan.
- We have received ... past tense, so we already have it.
- an inheritance from God ... what is it that we have inherited? Salvation in Christ, or just a chance to earn our own salvation through human effort with eternal damnation the prize for failure?
- according to his plan ... Does God actually work out His plans and see them to completion, or does God just get the ball rolling and hope we can finish his work?
[Ephesians 1:12-14 NLT] 12 God's purpose was that we Jews who were the first to trust in Christ would bring praise and glory to God. 13 And now you Gentiles have also heard the truth, the Good News that God saves you. And when you believed in Christ, he identified you as his own by giving you the Holy Spirit, whom he promised long ago. 14 The Spirit is God's guarantee that he will give us the inheritance he promised and that he has purchased us to be his own people. He did this so we would praise and glorify him.
- God saves you ... implies nothing but flat out states that it is God that saves, so who is man to unsave?
- The Spirit is God's guarantee ... So is the Holy Spirit a guarantee or not? If He is a guarantee, then the Saints (who have the Holy Spirit) WILL persevere to the end and receive the inheritance (ETERNAL LIFE). If the Saints do not persevere then the Holy Spirit guarantees nothing.
[Romans 8:29-30 NIV] 29 For those God foreknew he also predestined to be conformed to the image of his Son, that he might be the firstborn among many brothers and sisters. 30 And those he predestined, he also called; those he called, he also justified; those he justified, he also glorified.
- Predestined to be conformed to the image of his Son ... Those that will ultimately be conformed to the image of Christ are SAINTS, so this extended sentence is about the Saints.
- those he predestined, he also called ... the Saints are all most assuredly called; no Saint remains uncalled.
- those he called, he also justified ... the Saints that are called are assuredly justified; no Saint remains unjustified.
- those he justified, he also glorified ... the Saints that are justified (by the blood of Christ) are most assuredly glorified; no Saint will remain unglorified.
- Throughout this, “those” always refers to exactly the same group of people ... the Saints that will be conformed to the image of his Son ... with their “perseverance” to glorification assured by GOD (the one who is doing all of the action in these verses.)
Thus the claim that “Perseverance of the Saints is not found anywhere in Scripture” appears to be false.
