Hypocrisy or holiness?

Audience One puts forward some challenging but valid teaching on church discipline:

God desires for His people to be pure and holy and to live a life of integrity in the world and before Himself. As the Apostle Peter has said, “You shall be holy, for I am holy” (1 Peter 1:16). When the church embraces strong Bible teaching and rejects being held to its standard, we have the spiritual chaos that is evidenced today. When we divorce biblical preaching from biblical living “it promotes hypocrisy, instead of holiness” says, John MacArthur. To illlustrate, I had an opportunity last week to share the gospel with a Muslim gentleman while my front brakes were being changed. Through the course of our conversation he said something very insightful and convicting; his number one bewilderment about Christians is “why do you all believe one thing and constantly live another?” This is a tremendous indictment against the church.

Yes, it is.
