Jesus described the Devil as one who does not hold to the truth and has no truth in him.  Falsehood is tied to his very existence.

Every single human being who has ever lived apart from Christ has followed the lies of the Devil.  It’s our default setting as human beings.  We are born into sin, we know nothing but sin, and we naturally follow the ways of the world and the ruler of the earth which is Satan himself.  

Our level of freedom from deception will be directly proportional to the depth of our relationship with Jesus! 

The goal is to eliminate as much deception from our lives as possible by living as closely connected to Jesus as possible.  As we walk closely to Him and live in obedience to Him we are susceptible to less and less deception in our lives.  Only in heaven will we know the truth completely but we can live lives of freedom on this side of eternity as well!
