Mathew 7:15-16

​Watch yourselves, be on your guard, for satan will work you over like a rib with barbecue sauce if you're not careful and prayed up .

So, don't fall into his schemes, he'll build a story of lies and put it right in your mind or (someone else's), and without wisdom or (guidance) from the Lord, it will be difficult for you to decipher which is True or false. 

“Beware of the false prophets, [teachers] who come to you dressed as sheep [appearing gentle and innocent], but (inwardly) are ravenous wolves.  By their (fruit) you will (recognize) them." 
Mathew 7:15-16
