The list could go on and on. Satan is a master at making God's directions look foolish and unreasonable, at making the present situation seem to be the exception, and at making his suggestions appealing and actually advantageous. Satan uses false teachers who pretend to be from God. For Satan himself is transformed into an angel of light. Satan is a master of masquerade.
Deceivers are behind pulpits.
First, we have the test of God's Word. Satan loves to distort the true Gospel. The true Gospel calls people to repent of sin, receive Jesus as their salvation, and follow Him as their Lord. Those who teach another Gospel are deceivers. Second, a true minister of God will call us away from the world toward God.
