"…and the prayer of faith will save the sick man, and the Lord will raise him up…"
This quote could reemphasize the point that faithful prayer always raises sick people to full health
This can only be viewed that way if you separate the part you quote above from the rest of the verse; the requirement of anointing and the laying on of hands by the elders (priests) of the Church.
I will look for the verses you have asked regarding suffering being a virtue. I know that the Saints have typically viewed this as part of the meaning of “taking up our own cross and following Christ.”
The person seems to feel that anyone can heal themselves by simply declaring it. However St. Paul says something that suggests otherwise.
1 Corinthians 12:12-14, 27-31: For as the body is one and has many members, and all the members of the body, many as they are, form one body, so also it is with Christ. For in one Spirit we were all baptized into one body, whether Jews or Gentiles, whether slaves or free; and we were all given to drink of one Spirit. For the body is not one member, but many. Now you are the body of Christ, member for member. And God indeed has placed some in the Church, first apostles, secondly prophets, thirdly teachers; after that miracles, then gifts of healing, services of help, power of administration, and the speaking of various tongues. Are all apostles? Are all prophets? Are all teachers? Are all workers of miracles? Do all have the gift of healing? Do all speak with tongues? Do all interpret? Yet strive after the greater gifts.
Not all have the gift of healing. Now, one might suggest that he is referring to healing others, but it doesn’t actually say that. It is referring to the gift of healing itself; and not everyone has it.
