False and deceptive miracles can be so well masked and can occur in the guise of such outward piety, that detecting their false character can be overwhelmingly difficult.
Matt. 24: 4,24: Take heed that no man deceive you... For there shall arise false Christs, and false prophets, and shall show great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
