In this text, Paul gives examples of what it means to put off the old self and put on the new one in the Christian life. This sermon covers most of his examples under this question: what words should we speak? It places that theme into the contemporary context where words can go more wide and deep than ever before. It also gives questions that will help the Christian discern what words are appropriate when, as we live for the Lord who was and is our fragrant offering and sacrifice to God.
