Jesus demonstrated the will of God perfectly. Jesus’ works are the Father’s works. He came to show us the Father. So, let’s look at how Jesus revealed the will of the Father as it relates to healing. In Mathew 9:35. we read that Jesus healed every sickness and every disease among the people. Does that say to you that the Father might heal some people and not heal others? Of course not! The reason Jesus healed every single person in all the cities that He went to was because it must clearly be the will of the Father to heal every sickness and every disease! Sickness is a curse. God is not using sickness to teach you anything. God is not doing anything other than healing sickness!
Sickness can be demonic in its source, but not always of course. In Mathew 12:22 we read “Then one was brought to Him who was demon-possessed, blind and mute; and He healed him, so that the blind and mute man both spoke and saw.” Jesus healed this man of blindness and muteness by casting the devil out. Likewise, God has given believers the authority over all the power of the enemy!
Healing wasn’t just for Jesus to minister. In Matthew 10, Jesus sends out the twelve apostles to heal the sick, cleanse lepers, raise the dead, and cast out demons. And it wasn’t just the apostles! In Luke 10 Jesus sends out 70 others to heal the sick. Likewise in John 14:12 Jesus says those who believes in Him will do what He did and beyond. Finally in Mark 16:14-18 Jesus said “And these signs will follow those who believe.” He said those signs will follow those who believe!
Some believers say “doesn’t the Word teach that we are to suffer for the sake of the gospel?” It sure does! But if you look at it and allow Scripture to interpret itself, the Greek word for suffering is used 65 times to mean “suffering” and only one time does it refer to sickness and in that case Jesus said it is a demon causing the suffering not God, and He cast him out. Sickness is not of God. The bible is very clear in the New Testament: when it is talking about suffering it is referring to trials, tribulation and persecution - never sickness, not even poverty. Those are considered a curse and God doesn’t put curses on His children. Difficulty, however, is not a curse. God will use situations to develop character in us.
Some will ask about Paul’s “thorn in the flesh.” When we read these Old Testament verses we see that Paul was using Old Testament language in describing his “thorn in the flesh”. In Joshua 23:12-13, Numbers 33:55, and Judges 2:1-3 “thorns in sides” refers to people who harass you. Paul mentioned his thorn in the flesh in 2 Corinthians 12:7. Paul was describing people who were harassing him in every town he went into. (2 Cor. 11) What Paul is saying is that satan was stirring up people to attack him everywhere he went. This was not a matter of God trying to keep him from being prideful; it was the devil keeping him from being exalted by buffeting him, and he called it a thorn in his side.
How can we just know for certain that healing is the will of God? If you just need a couple of scriptures, look at Isaiah 53:4-6, where you can see very clearly that sin and sickness were paid for on the Cross. And then if you think that healing for sickness referred to in Isaiah 53 wasn’t real physical healing (that perhaps it was just spiritual healing), thank God we've got Mathew 8:17-18. In Matthew 8, Jesus casts out demons and He heals all the sick that it might be fulfilled which was spoken by Isaiah in Isaiah 53. There is also 1Peter 2:24 which says, “Who bore our sins on his own body on the tree that we having died the sin might live for righteousness by whose stripes you were healed.” God paid the price for you and I to be physically healed and walking in health our whole life.
Finally, someone might say well then how are you supposed to die? Psalms tells you how. He takes away your breath. That’s how we’re supposed to go. When it’s time to go, He takes away your breath. Nowhere in Scripture can you find that you are supposed to die of cancer or diabetes or some other sickness. You are supposed to die well, healthy, and strong! And then you say “Lord, my work is done, I am out of here.” And He will say “OK, come be with Me!” And you check out nice and peacefully in the middle of your sleep.
