And heal the sick that are therein, and say unto them, the kingdom of God is come nigh unto you. (Luke 10:9)
For he doth not afflict willingly nor grieve the children of men. (Lamentations 3:33)
Sanctify them through thy truth: thy word is truth. (John 17:17)
While it is true that we often get into the Word more during a sickness, it is not necessary to have sickness in order to grow spiritually.
And we know that all things work together for good to them that love God, to them who are the called according to his purpose. For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren. (Romans 8:28-29)
"If you have seen me, you have seen the Father." (John 14:9)
He said this because He did the work and will of the Father. If you ever wonder whether or not God wants to heal, you have only to look at our Lord's actions.
"Thy kingdom come, Thy will be done in earth, as it is in heaven." (Matthew 6:10)
There is no sickness and disease in Heaven, so we can pray confidently against it on earth knowing it is not His will. Jesus never prayed "heal if it is Your will, God." The only time He prayed "If it be Thy will" was in relationship to His own submission to the plan of God for His life--not healing. "If it be Your will" destroys faith. When it was used by an outcast leper who did not know Christ's will in healing, Jesus corrected his uncertainty by assuring him, "I will."
And, behold, there came a leper and worshipped him, saying, Lord, if thou wilt, thou canst make me clean. And Jesus put forth his hand, and touched him, saying, I will; be thou clean. And immediately his leprosy was cleansed. (Matthew 8:2-3)
Never turn God's facts into hopes or questions. Act on them as realities and you will find them powerful.
Therefore we are always confident, knowing that, whilst we are at home in the body, we are absent from the Lord: (For we walk by faith, not by sight:) We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord. Wherefore we labour, that, whether present or absent, we may be accepted of him. (II Corinthians 5:6-9).
→ "This is an affliction of the righteous" Some people claim: "Many are the afflictions of the righteous. This is an affliction you must bear because you are righteous."
Is any among you afflicted? let him pray. Is any merry? let him sing psalms. (James 5:13)
Although you can ask others to pray with you, they are not called to pray all your troubles away.
Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord: (James 5:14).
The sick are to be saved (from their physical sickness), raised up (return of strength), and forgiven of sin (spiritual healing).
