Galatians 6:7 KJV Be not deceived;
2 Timothy 4:3 KJV
 For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
Allowing oneself to be deceived is as bad as deceiving others. Ignorance is no excuse. We have the responsibility of acquiring adequate and relevant knowledge of the world around us. “Let not then any one deceive you, as indeed you are not deceived, inasmuch as you are wholly devoted to God” (Ignatius).
