What the speaker of this statement implies is that, it is only God that can heal Lady Macbeth of her disease, the earthly doctor can only do little for her in her condition. The sickness of Lady Macbeth is essentially of the mind and not of the body, so it is only God who can heal her and restore her health.

Antagonist: Amy Dunne in Gone Girl by Gillian Flynn
