Our hypocrisy doesn't fool God. It's in the Bible, Luke 16:15, TLB. "Then He said to them, 'You wear a noble, pious expression in public, but God knows your evil hearts. Your pretense brings you honor from the people, but it is an abomination in the sight of God."
Hypocrisy has questionable motives. It's in the Bible, Matthew 6:2, TLB. "When you give a gift to a beggar, don't shout about it as the hypocrites do—blowing trumpets in the synagogues and streets to call attention to their acts of charity! I tell you in all earnestness, they have received all the reward they will ever get."
Hypocrisy is knowing the truth but not obeying it—claiming Christ as Lord without following him. It's in the Bible, Matthew 23:13, NIV. "Woe to you, teachers of the law and Pharisees, you hypocrites! You shut the kingdom of heaven in men's faces. You yourselves do not enter, nor will you let those enter who are trying to."
