Hypocrisy (acting like you’re something you are not) is a horrible sin that has plagued the church, and mankind, since Adam fell. God dealt very severely with hypocrisy during the birth of the church. In Acts 5 Ananias and Sapphira were making a pretense of giving everything to God, and yet were holding back, obviously by agreeing between themselves to lie. So peter, exercising the gift of discernment, challenged Ananias. “Why would you pretend to give everything to God when you are holding back?” Notice that Peter told Ananias that he was lying to the Holy Spirit. Peter explained that he had not lied to man, but to God. Lying to the Holy Spirit is the same as lying to God, the Holy Spirit is God, one of the three Persons of the Trinity, and He exercises the power of God. Ananias and Sapphira paid the highest price for this hypocrisy.
