Can demons perform miracles?
Question 08128
The question of whether demons can perform miracles touches on something that matters deeply for discernment in the life of the church. If the answer is a straightforward no, then the supernatural becomes a reliable indicator of divine activity. If the answer is more nuanced, as Scripture suggests it is, then believers need to think carefully about what counts as evidence of God’s involvement in any given event.
What Scripture Actually Shows
The biblical evidence is that demonic beings can produce genuine supernatural phenomena, though not without boundaries set by God. The magicians of Pharaoh’s court replicated several of Moses’ signs through what the text calls “secret arts” (lahatim and latim). They turned staffs into serpents (Exodus 7:11–12), water into blood (Exodus 7:22), and produced frogs (Exodus 8:7). These were not stage tricks or psychological illusions. The text presents them as real supernatural occurrences, though it is equally clear that the magicians reached a hard limit when God’s power exceeded anything they could imitate (Exodus 8:18–19). Their own admission is telling: “This is the finger of God.”
In the New Testament, Paul warns that the coming of the lawless one will be “by the activity of Satan with all power and false signs and wonders” (2 Thessalonians 2:9). The word translated “false” here is pseudos, which can mean either that the signs are counterfeit or that they serve a lying purpose. Both senses are likely in play. The signs are real enough to deceive, but their purpose is to draw people away from the truth. Revelation 13:13–14 describes the False Prophet performing “great signs, even making fire come down from heaven,” and doing so specifically “in the presence of the beast,” with the stated aim of deceiving those who dwell on the earth. Again, the signs are presented as genuinely impressive, not as parlour tricks that only the gullible would accept.
Miracles, Signs, and the Distinction That Matters
There is a question worth pressing here about what we mean by “miracle.” If the word refers narrowly to an act that can only be performed by the Creator, such as creating life from nothing or raising the dead by intrinsic authority, then demonic beings cannot perform miracles in that strict sense. They are creatures, not the Creator. They cannot speak worlds into existence, and they do not hold the keys of life and death. What they can do is manipulate the natural and spiritual order in ways that produce effects beyond ordinary human experience, effects that look miraculous to observers who have no way of distinguishing the source.
This is precisely why Jesus warned that “false christs and false prophets will arise and perform great signs and wonders, so as to lead astray, if possible, even the elect” (Matthew 24:24). The warning presupposes that the signs will be impressive enough to constitute a genuine test of discernment, not an obvious fraud. If demonic signs were always transparent fakes, there would be no danger and no need for the warning. The fact that Jesus speaks of them leading people astray, potentially including the very elect, tells us something about their persuasive power.
The Boundaries of Demonic Power
Scripture is consistent in showing that demonic supernatural activity operates within limits established by God. Job’s story is the clearest illustration: Satan could do nothing to Job without divine permission, and the specific boundaries of that permission were set by God and enforced absolutely (Job 1:12; 2:6). The Egyptian magicians reached a point where their abilities simply stopped. The demons Jesus encountered were subject to His authority without exception, and they knew it, often crying out in recognition of who He was before He even addressed them (Mark 1:24; 5:7).
This means that while demonic beings can produce supernatural phenomena, they are never operating as free agents with unlimited power. They are finite creatures acting within the constraints that God, in His wisdom, permits. Their power is real but derivative, borrowed from the created order they inhabit and always subject to the authority of the One who made that order. The fact that God permits demonic supernatural activity at all serves His purposes, including the testing and refining of His people’s discernment.
Why This Matters for Discernment
The practical consequence is that the mere presence of the supernatural is never, by itself, proof that God is at work. This has enormous implications for how believers evaluate claims of miraculous activity in the church. A healing, a sign, a dramatic spiritual experience may be genuinely supernatural without being genuinely from God. The test is never “Did something supernatural happen?” but rather “Does the message accompanying this sign align with Scripture? Does it glorify Christ? Does it draw people toward the gospel or away from it?”
Moses gave Israel exactly this test in Deuteronomy 13:1–3. Even if a prophet gives a sign that comes true, if the message leads people toward other gods, the prophet is to be rejected. The sign’s reality is not disputed; its source and purpose are. John echoes this in 1 John 4:1: “Do not believe every spirit, but test the spirits to see whether they are from God.” The assumption behind this command is that not every spirit claiming divine origin actually has it, and that the testing must be grounded in something more reliable than the impressiveness of the experience itself.
So, now what?
Believers should take the reality of demonic supernatural activity seriously without being either fascinated by it or paralysed by it. The existence of counterfeit signs does not diminish the reality of genuine miracles performed by God; it simply means that discernment is not optional. The standard for evaluating any supernatural claim remains the same: does it align with Scripture, does it point to Christ, and does it produce the fruit that the Spirit of God produces? Where those tests are applied honestly and consistently, the counterfeit will be exposed, because the one thing demonic power cannot do is produce genuine conformity to the character of Jesus.
“Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world.” 1 John 4:1
