Jeremiah 17:14
I have seen his ways, and will heal him.
Isaiah 57:18
"It is the sole prerogative of God to remove spiritual disease.
Natural disease may be instrumentally healed by men, but even then the honor is to be given to God who giveth virtue unto medicine, and bestoweth power unto the human frame to cast off disease.
As for spiritual sicknesses, these remain with the great Physician alone; ....and one of the Lord’s choice titles is Jehovah-Rophi, the Lord that healeth thee.
He who made man can restore man;
He who was at first the creator of our nature can new create it.
My soul, whatever thy disease may be, this great Physician can heal thee."
Charles Spurgeon
