God can't regenerate our spirit before we know His will, because salvation is by faith, by trusting His known will.

Being healed is like being saved physically.
God sent His word and healed them and delivered them from all their destructions. Psalm 107:20. All His work is done in faithfulness to His promises.
God is not a man that He should lie: neither the son of man that He should repent: has He said and shall He not do it" or has He spoken and shall He not make it good? Numbers 23:19
Faith is expecting God to do what He has said in His word that He will do. It's believing that He speaks the truth.

God never asks us to believe He will do something for us unless He has promised to do it.

Faith comes by hearing the word of God. Romans 10:17 It can't come any other way.
If we see that the promises in God's word regarding healing are for us and that if we will act upon God's word we can expect Him to make it good in our life.
Disease make slaves of those who care for the sick. They are robbed of joy and rest. Sickness is not of love, God is love.

Disease is our enemy, robber. Do not tell others that disease is the will of God. It is hate and is the will of satan. If disease is God's will, then heaven will be filled with sickness. And we know there is no sickness in heaven.
The reason for Christ bearing our sins was to make righteous all who would believe in Him as their sin bearer. 

The reason for Him to bear our diseases was to make well all who would believe in Him as their disease bearer.
Christians are not to be sick. God wants us well.

We are to see our sins forgiven and our sicknesses healed. We are to see deliverance for our bodies as well as for our spirit.
We see our sicknesses and our sins, laid on Jesus at Calvary and we know that if Jesus bore them, then we don't have to bear them.

If we need to bear them, then it was useless for Jesus to have bore them,but since the Bible says they were ours, then surely we do not have to bear them.
Our substitute, Jesus Christ, was made sick and sinful for us. We know that neither sin nor sickness can be laid on us because Jesus bore them all on the cross for us. But this doesn't come automatically, it comes by putting our faith in what Jesus did for us.
Who his own self bore our sins in his own body on the tree, that we, being dead to sins should live in righteousness; by whose stripes you were healed. 1 Peter 2:24

We know that healing for the body is provided in the same redemption as salvation for the spirit. In redemption, there is both physical and spiritual healing.

If we are saved, we are healed!
When cloths were sent from Paul to the sick, they were laid on them with the same faith that they would have used had Paul personally laid his hands on them and ministered to them.
Easter

God did special miracles by the hands of Paul: so that from his body were brought to the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them.
Faith in God's Word always brings the answer. 

Thank Him for healing from the very moment that the hands of believers are laid on you in Jesus' name.
When a believer lays hands on you in Jesus' name and earnestly prays for your healing, believe the word of God; believe that Jesus spoke the truth when He said, "They [you] shall recover".
Faith has nothing to do with feeling. Feeling has nothing to do with faith.

Faith  has everything to do with what the word of God says, not regarding pains, symptoms or feelings.
John 5:14 Afterward Jesus findeth him in the temple, and said unto him, Behold, thou art made whole: sin no more, lest a worse thing come unto thee.
John 5:13 And he that was healed did not who it was: for Jesus had conveyed himself away, a multitude being in that place.
