Reason number thirteen we are sure it is God’s will for all to be healed is because of the eternal fatherhood of God. Who He is, His character, and His ability—is His patience, which is part of His love. He is slow to get angry, of great mercy, long-suffering, kind, and ready to forgive. He looks over all of His children like a father does his child because that’s what we are. We are His children, and He is our Father, Matthew 7:9-11.
Reason number twelve we are sure that it is God’s will for all of us to be healed is because of the firstfruits of the Redemption. Another way of saying it is “the earnest of our inheritance” (the firstfruits, a little foretaste of the resurrection). All you have to do is look at Jesus’ ministry in Matthew, Mark, Luke and John, He had healing lines that lasted all day. Healing was a big part of Jesus’ ministry.
Reason number eleven we are sure it is God’s will for all to be healed is because healing is a part of redemption. Just as much as being saved from hell, and just as much as being born again, healing is a part of redemption. It belongs to you equally with the forgiveness of sin, 1 Peter 2:24.
Reason number ten we are sure it is God’s will for all to be healed is because of the types of redemption. The things that are written in the Old Testament, all the things that happened with God’s people in the first covenant, are written as types for us. They typify, or portray, what has been fulfilled in the new covenant, the New Testament. 
Reason number nine we are sure it is God’s will for all of us to be healed is because sickness is part of the curse of the Law from which Christ has redeemed us, Galatians 3:13-14.
Reason number eight goes right along with the reason seven we are sure it is God’s will for all of us to be healed because of all the eternal names of God.
Reason number seven we’re sure it’s God’s will for all of to be healed because of the covenant of healing. Exodus 15:26 He said, “I Am Jehovah-Rapha. I Am the Lord Who heals you, Who mends you, Who restores you to normal.”

Reason number six we are sure it’s God’s will for all to be healed is because sickness is a work of the devil. Acts 10:38 says, “How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good…” Did He ever do any evil? Of course not. He only did good, and what was part of the good He was doing? “He went about doing good and healing all that were oppressed of the devil; for God was with Him.”
Reason number five we are sure it is God’s will for all to be healed is because of the origin of sickness. Romans 5:11-12 tells us. He said, “…but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement, wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned.”
Reason number four we are sure it’s God’s will for all of us to be healed is because of heaven—His will for heaven and the world to come, Matthew 6:10, His will is to be done on earth as it is in Heaven.
Reason number three why we are sure it’s God’s will for all to be healed is because of the original creation. Every thing God created was "very good", Genesis 1:1-31, no where in Genesis did God create sickness or disease.
Reason number two why we are sure it is God’s will for all to be healed is found in Proverbs 18:14. It says, “The [strong] spirit of a man will sustain his infirmity; but a wounded spirit who can bear?”
Reason number one we are sure it’s God's will for all to be healed today is because God’s Word is medicine, Proverbs 4:20-22. the word is life, health and medicine to all their flesh.
A joyful heart is good medicine, but depression drains one’s strength.
Pleasant words are as an honeycomb, sweet to the soul, and health to the bones.
Then a woman came up behind Jesus and touched the edge of his clothes. She had been suffering from chronic bleeding for twelve years. She thought, “If I only touch his clothes, I’ll get well.”

When Jesus turned and saw her he said, “Cheer up, daughter! Your faith has made you well.” At that very moment the woman became well.
A synagogue leader came to Jesus while he was talking to John’s disciples. He bowed down in front of Jesus and said, “My daughter just died. Come, lay your hand on her, and she will live.”

Jesus and his disciples got up and followed the man.

Jesus came to the synagogue leader’s house. He saw flute players and a noisy crowd. He said to them, “Leave! The girl is not dead. She’s sleeping.” But they laughed at him.

When the crowd had been put outside, Jesus went in, took her hand, and the girl came back to life.
Jesus got into a boat, crossed the sea, and came to his own city. Some people brought him a paralyzed man on a stretcher.

When Jesus saw their faith, he said to the man, “Cheer up, friend! Your sins are forgiven.”

Then he said to the paralyzed man, “Get up, pick up your stretcher, and go home.” So the man got up and went home.

When the crowd saw this, they were filled with awe and praised God for giving such authority to humans.
In the evening the people brought him many who were possessed by demons. He forced the evil spirits out of people with a command and cured everyone who was sick. 

       So what the prophet Isaiah had said came true: “He took away our weaknesses and removed our diseases.”
