Paul confronts the false teachers in this passage at the church of Colossae who were teaching that immorality and asceticism was acceptable because the body is evil. Paul tells us that if we desire to have an ongoing, intimate relationship with Jesus, we need examine and guard our hearts. He puts this in very strong language. He gives us some heavy things to consider which requires an honest examination of our own hearts. This message is not meant to give us a formula, but some practical guide lines to help us live in Christ and grow spiritually from the inside out.
