One of the first facts that becomes clear when one reads the accounts of Jesus casting out demons and healing is that very often they were both closely related. It is important to understand this more fully.
LESSON FOR TODAY: There is often a strong relationship between spiritual deliverance and physical healing. Often physical problems are also gone when the demons leave. That is because it was the demons who were causing the physical problems. Examples of these in the Bible include: crippled limbs (Luke 13:11), Paul’s thorn in the flesh (eye disease? – II Corinthians 12:7), muteness (sometimes dumbness, too – Matthew 9:32-33; 12:22; Mark 9:17-18,24-25), blindness (Matthew 12:22), seizures (Mark 1:26; 9:17-18,20,22,25; Matthew 17:15,18; Luke 9:39), deafness (Mark 9:17-18,20,25), sores (skin cancer?) (Job 2:7), boils and other painful afflictions (Psalm 78:49 – the plagues in Egypt were demon-caused), and physical torments of all kinds (Revelation 9:5,10). The Bible states that Satan can cause illness (Job2:7-8), even death (Job 1:19).
Physical healing can be a result of deliverance. If any of the demons who were removed were causing physical problems those problems will be resolved when the demons are removed. Generational spirits can cause the same ailments from generation to generation. Physical problems are usually not God’s main concern, rather He is more concerned for the spiritual condition of the heart. We often pray for the symptom (physical problem) to be removed while God wants us to seek Him and what He is trying to teach us through it. Paul’s thorn in the flesh is a clear example. It wasn’t God’s will for that demon to be removed, but for Paul to be spiritually strengthened through the experience.
If a physical problem is present it is helpful to find out when it first started and what else was going on at that time. Instead of focusing on removing the physical symptom, look for the root cause, be it demonic, spiritual or whatever else it may be.
Jesus often cast out demons and cured illness at the same time. Jesus said he would do this (Luke 13:32). He did this at the start of His ministry (Matthew 4:23-24; 8:16; Mark 1:34; Luke 4:41), around Tyre and Sidon (Mark 3:10-12; Luke 6:18-19), and in the middle of His ministry (Luke 7:21). Many female followers of Jesus were cured of both (Luke 8:2).
Even more precise are the accounts of when Jesus both cast out demons and healed illness in a person at the same time (Mark 6:13; Acts 5:16). Philip did this in Samaria (Acts 8:7) and Paul did it in Ephesus (Acts 19:12).
It must be noted that not all illness is demonic in origin. Jesus healed physical ills that weren’t demonic (Matthew 4:23-24; 8:16-17 fulfilled Isaiah 53:4; Mark 1:34; Acts 10:34; etc.). The Bible clearly talks about illnesses that are not demonic: severe pain (Matthew 4:24), seizures (Matthew 4:24), paralysis (Matthew 4:24; Acts 8:7), leprosy (Matthew 10:8), blindness (Luke 7:21), crippled limbs (Acts 8:7) and many other various diseases (Matthew 4:24). The fact that some physical ailments are on both lists (like seizures) shows that many ailments may have demonic or natural causes. They could be from one source or the other.
