If you listen carefully to the voice of the LORD your God and do what is right in his eyes, if you pay attention to his commands and keep all his decrees, I will not bring on you any of the diseases I brought on the Egyptians, for I am the LORD, who heals you. (Exodus 15:26, NIV)
Another great blessing is healing. In Exodus 15:26, God says that He will not bring down the plague on us, like He did on Egypt, if we obey His Word and walk in righteousness. There is no disease God cannot cure, because the Lord heals us, but the one who gives disease is also God.
The Bible takes many examples in which the Lord healed many kinds of diseases that could never be treated in the world. Second Kings 5 introduces Naaman, the commander of the army of the king of Aram. The Lord made Naaman very honorable, but he had leprosy. His illness was apparently a big burden to him because people considered it unclean. In the meantime, he was told by a young girl who was taken captive from Israel that if he would meet Elisha, the man of God, he would be cured. He immediately prepared much money and expensive clothes and visited Elisha with his servants. He arrived at Elisha’s house and waited for him, but Elisha did not go out to welcome him. Elisha simply sent a messenger to say, “Go, wash seven times in the Jordan, and your flesh will be restored, and you will be cleansed.” Commander Naaman was quite unpleasant at Elisha’s response, because he expected that Elisha would face him in person and then put his hand on his skin and pray to God for his illness. However, the way Elisha suggested seemed too simple but also impractical, so he got angry and left quickly. He, of course, did not do what Elisha said.
Then, his servants persuaded Naaman to go to the Jordan and do as Elisha said. He reluctantly went to the river, and then he dipped himself in the Jordan seven times, as Elisha taught. At that point, an amazing miracle happened. His flesh was restored and became clean like that of a young boy. Naaman realized Elisha was a real man of the Lord. He went back to Elisha to express deep gratitude. Also, he confessed that there was no god besides God in the world. What Naaman did was simply to listen to a girl and go to Elisha and then do what Elisha said. A small act of faith caused an astonishing miracle. His illness, which the world could not treat, was healed. Jehovah Rapha! Naaman experienced our healer God.
What Jesus did during his public life was to preach the gospel and heal the sick. There was no illness Jesus could not fix. He opened the eyes of the blind, made the disabled stand and walk, healed the epileptic and hemorrhagic patients, cured the paralyzed, and even saved the dead Lazarus.
Jesus’s healing was not limited to physical disease. He also cured patients possessed by an evil spirit, which was like a mental illness. In Mark 9, one boy was possessed by an evil spirit, so he became mute. The boy was thrown to the ground, foamed at the mouth, gnashed his teeth, and became rigid. The Bible says those symptoms were caused by an evil spirit, but it is not recorded whether his parents had seen the spirit. However, when the boy stood before Jesus, the evil spirit saw Jesus, and Jesus also saw it. Jesus knew what the spirit was and said to it, “You deaf and mute spirit! I command you, come out of him and never enter him again.” The spirit left the boy soon, and he was healed.
In Mark 9:23 and 29, Jesus asks two things for those who desire to be healed by the Lord: prayer and faith. Jesus said in verse 23, “Everything is possible for him who believes” and in verse 29, “This kind [of evil spirit] can come out only by prayer.” Jesus heals the sickness of those who ask in faith.
In addition to these, there are many other references to healing in the Bible. James 5:15–16 says that prayer in faith will make the sick person well and God will raise him up. It also says that if you confess your sins to each other and pray for each other, you may be healed. If you ask God in faith for relief from a disease the world cannot heal, God will surely give you a miracle of healing.
