1 I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. 2 Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. (Romans 12:1-2 ESV)
Deception is our enemy’s most powerful weapon. When a person is deceived into believing a lie they are not intending to participate in something that is wrong. No, they believe they have the truth and all those who oppose what they believe are just wrong. When the lie leads people to believe that their form of ‘religion’ is true Christianity, regardless of how unbiblical it is, they are not actually intending to be evil following an evil system. They are ‘sure’ they have the truth. They are sincere. I am sure the priests of Baal whom Elijah defeated at Mount Carmel were sincere as well.
