Further, is there a single documented case in history of satan ever healing anyone? What reason would satan have for healing someone?
1 If there arises among you a prophet or a dreamer of dreams, and he gives you a sign or a wonder, 2 and the sign or the wonder comes to pass, of which he spoke to you, saying, Let us go after other godswhich you have not knownand let us serve them, 3 you shall not listen to the words of that prophet or that dreamer of dreams, for the LORD your God is testing you to know whether you love the LORD your God with all your heart and with all your soul.
