Dear Classik, from my view of this thread I do not see who you quoted.
I would have to disagree with you on this because Christians do get sick and are even told of them in James 5:14," 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."
And then I read of Paul's fellow worker in the gospel in:
Philippians 2:27 For indeed he (Epaphroditus - a servant of Christ in the gospel) was sick nigh unto death: but God had mercy on him; and not on him only, but on me also, lest I should have sorrow upon sorrow.
Philippians 2:30 Because for the work of Christ he was nigh unto death, not regarding his life, to supply your lack of service toward me.
Surely we cannot be as Job's supposed comforters and find fault with him?
I have a very dear brother in the Lord who made the following statement concerning healing:
If we were to say that a healing came from God, the healing would have had to be instant, complete, permanent, witnessed and testified to. Anything short of this is not from God but from other spirit creatures.
This is not always true for we read in:
Luke 17:14 And when he saw them, he said unto them, Go shew yourselves unto the priests. And it came to pass, that, as they went, they were cleansed.
2 Kings 5:10 And Elisha sent a messenger unto him, saying, Go and wash in Jordan seven times, and thy flesh shall come again to thee, and thou shalt be clean.
God is not subject unto our reasoning. He can use doctors, prayer warriors, and even me and other saints. I know without a doubt that God raised a one year old child from death when I laid hands on him after falling approximately ten feet onto his head; his head was completely sideways and immediately straightened up and he began crying.
In church service an older friend of mine that I took to church had rheumatoid arthritis so bad that a large growth had grown on his wrist and he could no longer use it, plus he hurt so bad that he had to cover with blankets even in the hot summer to generate enough heat to alleviate some of the pain. He was going to be baptized that night and I asked why he didn't ask for healing at the same time. Oh Eugene, I'm not sure I believe in that.
Long story short, I saw and felt the growth before he went forward, he did ask, the preacher prayed, the entire church broke out in praise, and when he put dry clothes on after the baptism he came back to sit with me, and the large hardened lump had disappeared and a small soft swelling only remained. Why? I do not know but within a week it was gone too. He was healed as he went.
Ever read the following? 1 Timothy 5:23 Drink no longer water, but use a little wine for thy stomach's sake and thine often infirmities.
How about Jeremiah 8:22 "Is there no balm in Gilead; is there no physician there? why then is not the health of the daughter of my people recovered?" In actuality the balm is Christ Jesus, and God is not limited in the cure.
Blessings in Christ Jesus.
