Notice that Jesus was "present to heal them."
Jesus has the power to heal.
He has the power to heal us.
It's not dependent on where, but who.
Consider Jesus' healing ministry in John 9:
"And as Jesus passed by, he saw a man which was blind from his birth. 2And his disciples asked him, saying, Master, who did sin, this man, or his parents, that he was born blind? 3Jesus answered, Neither hath this man sinned, nor his parents: but that the works of God should be made manifest in him." (John 9: 1-3)
Notice that Jesus speaks about "The work of God." He does not get caught up in "whose fault is it?"
If we want to lay blame simply on whose fault it is, start with Adam, and the fall of man which followed.
Also, notice that healing is based on Himself, not where.
Isaiah prophesied Jesus our healer:
"Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted." (Isaiah 53: 4)
The King of the Jews--and our Great High Priest--fulfilled and continues to fulfill this prophecy today:
"4And when Jesus was come into Peter's house, he saw his wife's mother laid, and sick of a fever. 15And he touched her hand, and the fever left her: and she arose, and ministered unto them. 16When the even was come, they brought unto him many that were possessed with devils: and he cast out the spirits with his word, and healed all that were sick: 17That it might be fulfilled which was spoken by Esaias the prophet, saying, Himself took our infirmities, and bare our sicknesses." (Matthew 8: 14-17)
Notice "Himself" took our diseases, Him who is ever-present (Hebrews 13:5)
Now, back to the account of John 9:
4I must work the works of him that sent me, while it is day: the night cometh, when no man can work. 5As long as I am in the world, I am the light of the world. 6When he had thus spoken, he spat on the ground, and made clay of the spittle, and he anointed the eyes of the blind man with the clay, 7And said unto him, Go, wash in the pool of Siloam, (which is by interpretation, Sent.) He went his way therefore, and washed, and came seeing." (John 9: 4-7)
Jesus our life and health, is ever-present to heal you, wherever you are, whatever your condition may be!
Don't worry about trying to be in the right place. Jesus is your healing, ever present to heal!
