The deeper we pray, the more we can focus on every part of the body, and ask the Holy Spirit to protect and heal our brains, ears, necks, lymph glands, throats (for the throat call on Saint Blaise), blood vessels, hearts, lungs (for the respiratory tract, Saint Bernardine), eyes (Saint Lucy), stomachs, intestines, colons, reproductive organs, breasts (for breasts, Saint Agatha), joints, and skin. [Here are thirty saints for common ailments].
Throughout life, our cells, tissues, and organs take a beating from the environment, bad nutrition, and simple age, so it's wise to go through one's life and pray to rectify potential health problems.
Also, pray you do not somaticize: let your fears and emotions manifest as physical affliction.
God is the Great Physician and each cell comes from the life force of His Spirit.
That Force can heal anyone of anything.
One must cooperate by casting away resentment, unforgiveness, and anger -- which also wear on our organs -- and so start a journey to health by going through a review of life and loving anyone we have not loved and forgiving everyone we have not forgiven, including ourselves.
Pray. Meditate on Scripture. Listen.
Ask Jesus to "reverse the clock."
Let's say you smoked: go back, ask the Lord to forgive you for smoking, cast out spirits that may be associated with nicotine, and ask Him to pervade your lungs with healing. "Soak" yourself in holiness.
Cast out spirits of "tobacco" and "addiction."
When you're pure inside, entities are not comfortable; Jesus called them "unclean spirits"; foul does not mesh with clean.
Your angels are there. Saint Raphael will come. If you drank too much, focus on your liver. If you ate the wrong things, focus on your colon (and stomach), if obese, cast out the spirit of gluttony. If there is a genetic weakness, ask the Lord to reconfigure your genes.
Do a life review of your health and pray over each organ, looking for blotches that may cause future problems, for the non-physical transmits to the physical and it is Grace that heals through deliverance. Look at how many times Christ cast out demons and unclean spirits before the healing took place!
If you have jealousy, this could produce bile (bitterness). If you're angry, you harden your heart (and its vessels; "Harden not your heart," Psalm 95:8). If you reject yourself, you may have acne. If your heart oozes "gall," go back through your life and neutralize this acid. (An acidic system is more prone to cancer.) If you've failed to forgive you may be attached in a "sick way" to whomever you have not forgiven.
It is often the spiritual garbage inside of us that attracts the "flies" that can carry disease and fester within.
Saint Teresa of Avila said (about the Light that gives us life) "it is not a radiance which dazzles, but a soft whiteness and an infused radiance which, without wearying the eyes, causes them the greatest delight; nor are they wearied by the brightness which they are seeing in this Divine beauty.
"So different from any earthly light is the brightness and light now revealed to the eyes that, by comparison with it, the brightness of our sun seems quite dim and we should never want to open our eyes again for the purpose of seeing it. It is as if we were to look at a very clear stream, in a bed of crystal, reflecting the sun's rays."
It's when we allow that light to dim or blur that trouble and breakdown begin.
God is the Great Physician. In deep quiet listen for Him. He reverses the curse; He reverses the letters in "evil" and turns them back into "live."
