The preacher delves into the concept of hypocrisy, which originated from Greek theater as the act of putting on a mask and playing a part on stage. In the New Testament, hypocrisy is portrayed negatively as deceit, insincerity, and pretense, where one's outward appearance contradicts their true intentions. Hypocrisy involves pretending to possess virtues or beliefs that one does not truly hold, leading to a false impression of one's motives. The sermon emphasizes the dangers of hypocrisy, warning that hypocrites will face severe consequences and that God detests this sin above all others.

T. Austin-Sparks reflects on the troubling incident involving Barnabas in Galatians 2:13, where even a 'good man' succumbed to dissimulation and hypocrisy, leading to a painful separation from Paul. Sparks emphasizes the importance of standing firm on truth and principle, warning against the dangers of compromise for the sake of popularity or acceptance. He highlights Barnabas's sociable nature and the tragic consequences of allowing personal temperament to overshadow the commitment to the Gospel. The sermon serves as a reminder to be true, honest, and transparent in our walk with God, rather than seeking to please men. Ultimately, Sparks calls for vigilance in maintaining integrity amidst the pressures of tradition and societal expectations.
