The healing of our diseases and sicknesses is included in Christ Jesus' work on the cross along with the forgiveness of our sins.
It is never God's will for our spirits to be sick, nor for our bodies to be sick!
God's will is that we be as healthy in our bodies as we are in our spirits.
John in 3 John 2 wishes above all things that you may prosper and be in health, even as your soul prospers.
God promises protection for our bodies as well as for our spirits if we will live in Him [Psalm 91].
The promise of salvation and healing are to all, without exception, whosoever believes in Him.
We are not to look at our symptoms but at the stripes that Jesus bore when He was whipped and beaten for our healings.
We are not to look to a preacher or any other, but to Jesus alone for healing or any other of God's promises.
We do not need to beg or make any deal with God for healing.

There is only one condition: Whosoever believes!
In Christ, we receive both forgiveness for our sins and healing for our bodies.
Both sin and sickness came into the world through the fall of the human race. We need to look for the healing of both in Jesus Christ our Savior.
God is both the Savior and the healer of His people.

It is always His will to save and to heal all those who believe on Him.
God's promises to heal are as much a revelation of His will as His promises to save are His revelation of His will.
The Bible shows the will of God concerning healing of the body just as clearly as it does the will of God concerning salvation. 

He doesn't need to give any special revelation. He has definitely promised healing to all.
If it is God's will for us to be well, then it is only logical that the best way is by divine means.
If its not God's will for us to be well, then it would be wrong to even look to get well through natural means.
Those who don't know God's will for their healing are doing all within their power of human skill to get well with the use of other means, whether it's His will or not.
Many people are wanting and waiting for God to give them a special revelation of His will for their healing.
Some see others healed, but question if healing is God's will for them.
