The lesson from these verses is to consider how we speak and reassess our whole concept of justice. Paul says, “Be careful how you express yourself.” If it is all about you, you will simply look like anyone else in the world – you have defeated yourself already. Secondly, Paul tells us that when we have to be very careful in how we treat our fellow brother and sister in Christ. If we rage against them before others who are not Christians we are defeating the impact of the gospel, and causing a stumbling block to people who might be immature in the faith or at least interested in the gospel. Churches filled with politics and divisions are not great places to bring up children, young people, or those who are new in the faith or immature in their faith or enquirers.
