The demon realm is true believe it , What is the realm of demons?

The Bible teaches the existence of an immaterial, spiritual reality, unseen by human eyes. The physical reality is evident for all to see—although some doubt the existence of a material universe, too! The Bible says that the spiritual realm consists of both good—God and the holy angels—and evil—the devil and his demons. Demons are most likely fallen angels who rebelled against God and were thrown out of heaven (see Ezekiel 28:11–17; Isaiah 14:12–15; Revelation 12:7–9).

The Bible also teaches that humans were created by God in His image, which means we have a spiritual component (Genesis 1:27). We are more than physical entities; we possess a soul/spirit destined for eternity. Even though the spiritual realm is invisible to the physical eye, we are connected to it, and what goes on in the spiritual realm directly affects our physical world.

The Bible teaches that our world is more than what we see with our natural eyes; there are two distinct realms—the spiritual and the natural.

The term demon is derived from the Greek word daimōn, which means a “supernatural being” or “spirit.” Though it has commonly been associated with an evil or malevolent spirit, the term originally meant a spiritual being that influenced a person's character.

The first line of the Bible states that heaven is created along with the creation of the earth (Genesis 1). It is primarily God's dwelling place in the biblical tradition: a parallel realm where everything operates according to God's will.

Delving into the supernatural can be exciting. The human mind is curious and always ready for additional information and the spiritual world, where demons and angels live, is vast. The supernatural world is an intriguing topic. Its inhabitants arouse curiosity, for just as their realm is invisible, they are also invisible and mysterious. In Christianity, the supernatural has a significant influence on the physical world, and demons and angels in the bible play a major role in the events that happen here on earth.

The phrase “heavenly places” or “heavenly realms” is used several times in the book of Ephesians (1:3, 20; 2:6; 3:10; 6:12). This phrase is translated from the Greek word epouranios, meaning “the sphere of spiritual activities.” “Heavenly realms” can refer to both angelic and demonic activity. Ephesians 1:20 says that God “raised Christ from the dead and seated him at his right hand in the heavenly realms.” But Ephesians 6:12 speaks of evil forces in the same realm: “Our struggle is not against flesh and blood, but against . . . the spiritual forces of evil in the heavenly realms.”

As flesh-and-blood humans, we have very little understanding of the spirit world. We cannot see, hear, or touch it. However, the Bible assumes it, and we can glean insight into a world we cannot see by studying what God tells us about it. First of all, God is spirit (John 4:24). He exists outside the bounds of time, space, and matter. His home is called heaven (Acts 7:55; Isaiah 63:15), but this is a distinct place, not to be confused with “the heavens,” referring to the atmosphere (Genesis 1:1; Psalm 148:4), or the “heavenly realms,” which encompass all spirit beings.

In God’s heaven, He sits on a throne (Matthew 23:22; Hebrews 4:16), surrounded by adoring angels (Revelation 7:11; Psalm 99:1) who exist to serve God and minister to His saints (Hebrews 1:14; Matthew 4:11; Genesis 19:1). Angels also have the ability to appear as men when sent to deliver messages from God (Genesis 18:2, 16–17; 19:1–2; Daniel 10:5–6).

Demons started out as angels in the Bible. They served God in Heaven. There was no evil in them. It is only after the devil (Lucifer) deceived them that they opted to follow him, which led to them rebelling against their creator. They sinned and evil took over their holy nature. Whatever the devil told them must have been so convincing that they saw the glory of God as a lie.

The fall of the demons is the first fall, the first introduction of sin to the universe. Before the fall of men (Adam and Eve), the devil and his demons fell, they sinned against God. The devil came to tempt Eve in the Garden of Eden from outside. Evil already existed in demons before it existed in men.

Darkness cannot co-exist with light, sin cannot co-exist with holiness. The evil angels had to be cast out of Heaven. They could not live in a holy place and contaminate it with sin. Michael and his army of angels threw the demons down to earth with their leader (the deceiver) Lucifer.

Mark 9:25-27 is a perfect example of the manifestation of the spiritual into the physical world. Jesus expels a dumb and deaf spirit. This evil spirit had possessed a young boy and caused him to be deaf and dumb. This suggests that demons can alter the condition of a human being. They wield that much power. This does not imply that demon possession causes all physical disabilities. The Bible offers one of many explanations for the cause of disability.

We find more interesting evidence from the Bible about the extent of demonic influence on human beings in Mark 5:1-13. This is a narration of the story of a man who was possessed by a being or group of beings that calls itself Legion. The name Legion refers to the thousands of demons that inhabit one man.

Demons can also possess (inhabit) human beings. Strong’s Concordance describes possession as the state of being under the power of a demon or evil spirit. During possession, the demon exerts influence on a human being and this spiritual influence manifests physically, emotionally, mentally, and psychologically.

So yes this is very real , we need to understand what is happening around us on a daily bases about light & darkness

However, the dark side of the heavenly realms belongs to Satan and his evil spirits. Satan is not the counterpart to God. God has no challenger. Satan is a created being who has only the power God allows him to have for only as long as God allows it (Isaiah 14:12; Luke 22:31; Revelation 12:12). Yet, for reasons known only to God, Satan and his minions are allowed to wreak havoc upon the earth and the servants of God—if unchecked by spiritual warfare and the holy angels.

Angels are sent to execute God’s purposes on earth. They are supernatural beings with extraordinary powers. They are portrayed as the good guys in the Bible. Hebrews 1:14 refers to angels as ministering spirits. Their permanent residence is in Heaven with God.

Daniel 10 gives us the best glimpse into what happens in this world we cannot see. An angel was dispatched by God to deliver a message to Daniel as he prayed, but the messenger was detained for three weeks by “the prince of Persia,” a demon (verse 13). The angel later told Daniel that he had to have help from Michael the archangel in order to prevail and continue on the assignment God had given him.

The ministering duties of the angels in the Bible are diverse. In Daniel 6:22, the angel’s role was to protect. They protected the prophet Daniel from being devoured by lions. On the other hand, an army of angels with horses and chariots of fire was sent to protect the prophet Elisha (2 Kings 6:15-17).

Angels in the Bible also rescue believers. Acts 12 records Peter’s miraculous escape from prison. It was during the early days of the Christian persecution when Peter was imprisoned for preaching the gospel. A powerful angel appeared to Peter in his prison cell, removed his shackles and helped him to escape

This glimpse into the heavenly realms helps us understand a few things. First, we learn that there is fierce warfare taking place at all times. Satan and his demons are actively working to thwart the plans of God and destroy whatever they can ( John 10:10). If a mighty angel on a mission from God could be detained by demonic forces, then demons must have great power. Second, God does not leave His children defenseless against this evil army.

Second Corinthians 10:4 says, “For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds.” Ephesians 6:11–17 tells us exactly what armor we need to stand firm against the temptations and schemes of the devil. In ourselves, we are no match for Satan’s devices. We need spiritual armor to fight spiritual battles. The third truth we can learn from the Daniel passage is that prayer gets God’s attention and that His answer is on the way. There are forces unknown to us that may interfere with God’s desire to aid us, and we must continue to persevere in prayer until the answer comes ( Luke 18:1; Ephesians 6:18).

The heavenly realms are as real as the earthly realms. We will spend most of our lives living in the heavenly realms (2 Corinthians 5:1; 1 John 5:11). In contrast, our earthly existence is only a “vapor that appears for a little while and is gone” (James 4:14). Physical battles may seem intense, but the results are temporary. However, spiritual battles have eternal consequences. When we live our earthly lives in recognition of the unseen battles that rage all around us, we will be more careful about what we say and do (Ephesians 5:15–16; 2 Corinthians 2:11).

In our culture, the most commonly accepted form of evidence for proving the existence of something is empirical evidence, which involves using the scientific method of observation and experimentation. Is there empirical evidence for a spiritual realm? It doesn’t take much research before one realizes there is “evidence” both for and against the existence of a spiritual realm. It comes down to which studies one wants to believe.

The best, and most prevalent, evidence available proving that there is a spiritual realm is testimonial evidence. We can look at the sheer number of religions around the world and the billions of people who focus their lives on the spiritual realm. Is it likely that so many people would report encounters with the spiritual and it not be real?

The best testimonial evidence for a spiritual realm is the Bible itself. Historians, both Christian and non-Christian, agree that the historical authenticity of the Bible is strong. Jesus claimed to be God’s Son, the One who came down from heaven. He made this fact quite clear: “You are from below; I am from above. You are of this world; I am not of this world” (John 8:23).

The Bible recounts numerous encounters that people had with the spiritual realm. Jesus cast demons out of people regularly, healed the sick by speaking to them, miraculously fed thousands of people, and spoke with people who should be dead: Moses and Elijah (Matthew 17:1–3). These are all indicators that the spiritual realm is real.

We will be faithful to utilize our weapons of prayer and the armor of God, knowing that the real battles are fought and won in the heavenly realms.
