Demons do "believe." James 2:19 is blunt about it; they believe that God is one, and they shudder. They know who Jesus is with a clarity that most humans never reach. They confess His identity, His authority, and are more than aware of His coming judgment. They even request (and sometimes receive) temporary mercies from Him.
Yet Scripture never once holds out the possibility of their salvation.
Hebrews 2:16 is as clear as it gets; "For surely it is not angels that he helps, but he helps the offspring of Abraham."
The entire logic of the incarnation, the atonement, and the high-priestly work of Christ is tied to human nature, and the redemption of the natural order that was cursed by mankind's disobedience. God created man in His image, and that's why the salvation of man is for his image-bearers alone. Jesus had to be made like His brothers in every respect so that He could make propitiation for the sins of the people (Hebrews 2:17). The cross is not a generic cosmic transaction; it is the Son of God taking on flesh and blood to destroy the one who has the power of death and to free "those" who were subject to lifelong slavery (Hebrews 2:14–15).
That "those" is humanity. Fallen angels are never described as image-bearers. They are never offered a covenant of grace. And they'd absolutely reject any idea that you should worship or venerate them for their closeness to God's throne.
It is the offspring of Abraham; human beings who share flesh and blood, who were made in the image of God, who fell under the curse through the first Adam, and for whom the last Adam took on the same nature. The incarnation is not some cosmic rescue operation that just happens to include humans. Salvation (grace) is the deliberate assumption of human nature so that propitiation could be made for the sins of the people. Angels and demons (fallen or unfallen) stand outside that economy.
Fallen angels and demons know this. Their knowledge is not theoretical. When they encounter the incarnate Son they do not negotiate for adoption or atonement. It never comes up.
Why?
It's simple, they were never image-bearers. They were never offered a Mediator. They were never elected unto salvation.
They acknowledge His authority and, at times, request temporary restraint of His judgment, or request relocation (the pigs, the "torment us not before the time" ). They never negotiate for adoption or atonement because those categories do not exist for them. The conversation never moves in that direction. That's all they get because the categories of covenant grace, justification, and inheritance simply do not apply to them.
This is also why any notion of venerating them; or treating their proximity to the throne as something to be honored, is foreign to the true biblical witness. They simply have no right to claim a special or specific position or purpose in the adjudication of Christ's kingdom goals. Even the holy angels refuse worship (Revelation 19:10; 22:9). The fallen ones are under judgment, kept in chains for the day of reckoning (Jude 6; 2 Peter 2:4). They do not present themselves as intermediaries or objects of reverence; they are adversaries whose end is already fixed. And you are not going to encounter them. They have no access to you. They are "restrained".
Scripture speaks of angels as a created order of spiritual beings (Psalm 148:2, 5; Colossians 1:16; Hebrews 1:14). And regarding spiritual warfare, the New Testament uses overlapping language for the hostile spiritual powers; "demons" "unclean spirits," "evil spirits," "the devil and his angels" (Matthew 25:41), and "principalities and powers".
So what are the demons?
A distinct class of fallen angels?
Disembodied spirits of the Nephilim?
A different class of beings altogether?
My view is they are an unnatural creation. Soulless. A hybrid offspring. An unnatural mixing. Not the original fallen angels themselves who are currently in restraint.

When the Nephilim died (whether in the Flood or later), their spirits had no legitimate place to go. They were not pure human souls that could enter Sheol in the normal way, nor were they angels that could return to the heavenly realm. The flood didn't destroy them. And they became the restless, body-seeking unclean spirits we see in the Gospels. They were never part of the human race for whom the Son took on flesh. And the categories of covenant, justification, adoption, and inheritance simply do not apply to them. These spirits are the residual, incomplete product of an illicit union. They are not full persons in the way humans are, nor are they the original angelic persons. They are a third, unnatural kind of existence; capable of belief, fear, speech, and desire for a host, yet outside the scope of redemption.
They know this, and they know Jesus.
So, knowing isn't necessarily saving.
Confessing is not inheriting.
Recognizing authority is not receiving grace.
This is why James 2:19 stands as a warning, not a puzzle. Demons believe, and shudder. Their belief is accurate, intense, and theologically correct as far as it goes. But for them it produces only terror. It never produces trust, repentance, or union with Christ, because those realities belong exclusively to image-bearers who have been given a Mediator.
So what can we learn from scripture that resolves this problem regarding what we can learn about the means of salvation for humanity?
The demonic example regarding belief is as orthodox as it gets. And James immediately contrasts that kind of belief with the living faith that justifies (James 2:20–24).
James 2:20–24
"But are you willing to acknowledge, you foolish person, that faith without works is useless? Was our father Abraham not justified by works when he offered up his son Isaac on the altar? You see that faith was working with his works, and as a result of the works, faith was perfected; and the Scripture was fulfilled which says, "And Abraham believed God, and it was credited to him as righteousness," and he was called a friend of God. You see that a person is justified by works and not by faith alone."
What "work" did Abraham do?
Abraham’s obedience in taking Isaac to Mount Moriah and raising the knife in readiness to sacrifice him. That was the work.
What makes it a "work of faith"?
A "work of faith" is an act that flows from a living trust in God rather than from self-reliance, fear, or an attempt to earn standing with Him. Its intent is not selfish. It's not something you could boast of.
With Abraham it arose from a prior trust in God’s promise. There was this relationship already in the works. God had already declared Abraham righteous on the basis of faith. And Isaac was the child through whom that promise would be fulfilled (not Ishmael, but that's for a different study). When God commanded Abraham to offer Isaac, the act required Abraham to trust that God would still keep the promise even if Isaac died.
So it's about obedience and sacrifice. Obedience to a specific word from God. It risks everything on God’s faithfulness. Human calculation says, "If Isaac dies, the promise dies." Faith says, "God will keep His word somehow." Its willingness to act against natural reasoning, yet still clinging to the promise, is what marks it as a work of faith rather than a work of the flesh or of the law.
His faith was "completed by his works." (James 2:22)
His faith matured, it became the fullest expression of faith. The inward trust became outwardly visible and confirmed. The work did not create the faith; it revealed and matured what was already there.
Paul uses the same category when he speaks of the "work of faith" (1 Thessalonians 1:3; 2 Thessalonians 1:11). It is never faith plus works as two separate saving ingredients. It is faith working because true, genuine faith is never alone.
True faith unites the sinner to the Son, a faith union bearing the fruit of obedience.
Amen?
