The concept of healing is very controversial in the Christian faith. So, I refer back to the Word for guidance.
26 And said, If thou wilt diligently hearken to the voice of the LORD thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the LORD that healeth thee.
The Lord can heal the people that society deems as unhealable, and deliver those who are perceived as undeliverable!
15 And the LORD will take away from thee all sickness, and will put none of the evil diseases of Egypt, which thou knowest, upon thee; but will lay them upon all them that hate thee.
19 Then they cry unto the LORD in their trouble, and he saveth them out of their distresses. 20 He sent his word, and healed them, and delivered them from their destructions
4 Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted. 5 But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
17 For I will restore health unto thee, and I will heal thee of thy wounds, saith the LORD; because they called thee an Outcast, saying, This is Zion, whom no man seeketh after.
So believe it, in Jesus Name!
