Here is a list of conditions that God has healed, and I was a personal witness to it.
These are first hand.testimonies, people healed in the name of Jesus, by the power of the Holy Spirit. I got to see it happen, or I am a personal friend of the person that experienced it. I am putting these on here in hopes that this may build your faith, and give you hope if you are fighting some kind of health issue.
These are listed in no particular order.
Irritable Bowel Syndrome
Degenerative Brain Disease
Spinal cord injury
Swelling and loss of movement in a thumb
Loss of feeling and loss of movement in a toe
Exposed nerve in a finger
Torn muscle in a shoulder
Uneven legs growing out to be even
If you are suffering with one of these, then just know that God's power heals your condition.
There are many ways to be healed. All of them are accomplished by the Holy Spirit working on your body.
You can be healed through your own faith (Mark 5:34)
You can be healed through the faith of a friend (Matthew 8:13)
You can be healed by having others pray for you (James 5:14-15)
You can be healed by commanding the condition to leave your body in the name of Jesus (Luke 4:39)
There are many other ways too. This is just to get your started. A good way to start is to believe that God is good, and that He is willing (Matthew 8:3). You can even ask Him to help you believe (Mark 9:24)
