Jesus defined discipling and "teaching them to obey all that I have commanded you" (Matthew 28:20). It is therefore important to know what Jesus did command.
My experience is that Christians, when asked, can think of very few things Jesus commanded. Some suggest that he did not command much. Some react to the word "commands" as if that is unworthy of Jesus. Listing His commands shows the opposite. It provides a checklist of key discipling topics covering every area of life. But, if Christians are not aware of Jesus commands, our discipling will inevitably be weak.
