“I have seen his ways, but I will heal him.” — Isaiah 57:18
It is the sole prerogative of God to remove spiritual disease.
Natural disease may be instrumentally healed by mortals, but even then the honor is to be given to God who gives virtue to medicine, and bestows power to the human frame to cast off disease.
As for spiritual sicknesses, these remain with the great Physician alone.
He claims it as His prerogative, “I put to death and I bring to life, I have wounded and I will heal”, and one of the Lord’s choice titles is Jehovah Rophi, the Lord that heals you.
“I will heal your wounds,” is a promise which could not come from the lips of a mortal, but only from the mouth of the eternal God.
On this account the psalmist cried to the Lord:
“O Lord, heal me, for my bones are in agony,”
and again,
“Heal me, for I have sinned against You.”
For this, also, the godly praise the name of the Lord, saying:
“He heals all our diseases.”
He who made us can restore us; He who was the Creator of our nature can new create it.
What a transcendent comfort it is that in the person of Jesus “all the fullness of the Deity lives in bodily form.”
My soul, whatever your disease may be, this great Physician can heal you.
If He is God, there can be no limit to His power.
Come then with the blind eye of darkened understanding, come with the limping foot of wasted energy, come with the maimed hand of weak faith, the fever of an angry temper, or the ague of shivering despondency, come just as you are, for He who is God can certainly restore you to health.
None shall restrain the healing virtue which proceeds from Jesus our Lord.
Legions of devils have been made to own the power of the beloved Physician, and never once has He been baffled.
All His patients have been cured in the past and shall be in the future, and you shall be one among them, my friend, if you would just rest in Him this night.
