That it might be fulfilled which was spoken by Esaias the prophet, saying, Himself took our infirmities, and bare our sicknesses.
Then you will ask in my name. I’m not saying I will ask the Father on your behalf, for the Father himself loves you dearly because you love me and believe that I came from God.
Keep on asking, and you will receive what you ask for. Keep on seeking, and you will find. Keep on knocking, and the door will be opened to you.
He personally carried our sins
    in his body on the cross
so that we can be dead to sin
    and live for what is right.
By his wounds
    you are healed.
But when people keep on sinning, it shows that they belong to the devil, who has been sinning since the beginning. 

But the Son of God came to destroy the works of the devil.
Let this mind be in you which was also in Christ Jesus,  who, being in the form of God, did not consider it robbery to be equal with God,  but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. 

And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross. 
And he could there do no mighty work, save that he laid his hands upon a few sick folk, and healed them.

And he marvelled because of their unbelief. And he went round about the villages, teaching.
And the whole multitude sought to touch him: 
for there went virtue out of him, and healed them all.
Even in his own land and among his own people, the Jews, he was not accepted. Only a few would welcome and receive him. But to all who received him, he gave the right to become children of God. All they needed to do was to trust him to save them.
And I have given you authority over all the power of the Enemy, and to walk among serpents and scorpions and to crush them. Nothing shall injure you!
The thief’s [satan] purpose is to steal, kill and destroy. 
My [Jesus] purpose is to give life in all its fullness.
You can never please God without faith, without depending on him. Anyone who wants to come to God must believe that there is a God and that he rewards those who sincerely look for him.
Is anyone sick? He should call for the elders of the church and they should pray over him and pour a little oil upon him, calling on the Lord to heal him.  And their prayer, if offered in faith, will heal him, for the Lord will make him well; and if his sickness was caused by some sin, the Lord will forgive him.
So if anyone eats this bread and drinks from this cup of the Lord in an unworthy manner, he is guilty of sin against the body and the blood of the Lord. 

That is why a man should examine himself carefully before eating the bread and drinking from the cup.  
For if he eats the bread and drinks from the cup unworthily, not thinking about the body of Christ and what it means, he is eating and drinking God’s judgment upon himself; for he is trifling with the death of Christ.  

That is why many of you are weak and sick, and some have even died.
 But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who dwells in you.
And you no doubt know that Jesus of Nazareth was anointed by God with the Holy Spirit and with power, and he went around doing good and healing all who were possessed by demons, for God was with him.
