"Liberated by the Revelation of Truth" -Scripture teaches us that Satan is the author of confusion. At what point did Satan assume the role as the author of confusion? When Satan spoke through the serpent to tempt Eve to consider her desires over God's will, it opened the hearts of all humans up to confusion after the fall into sin. Satan doesn't have to get us to believe a lie to make us ineffective as Christians. All that he has to do is get us to have a little doubt in our hearts about God and the truth and we'll become weak in the faith. Humans do not realize just how much we can allow Satan to do his evil work in our lives. Yet, he gets our cooperation to withstand us.
