"Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves. Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. Wherefore by their fruits ye shall know them." -Matthew 7:15-20
In the context of the verse above, I have trouble believing demons can heal others. Isn't healing a de facto good fruit? Or is there more to be said here? I can see the evil one working signs and wonders, but healing of illness seems to be good made manifest.
