The old man is not sent to the hospital?

from Spurgeon, "The Fourfold Treasure" #991

If any man is in Christ, he is not an old creature
mended up. He is a new creature. "Old things are
passed away; behold all things are become new."

That which becomes holy in us is the new life.

The old nature never changes into a holy thing.

The old man is not sent to the hospital to
be healed, but to the cross to be crucified.

The old nature is not transformed and improved,
but doomed to die and to be buried.
