This coming semester I am going to be teaching an elective at Logos School on practical Christianity. The students will be using a workbook I put together, Basic Christian Living, and which Canon has just published. There are short teaching sections interspersed throughout, along with questions and Scripture references to look up to answer the questions.
There are chapters on worship, confession of sin, restitution, contentment, and so on. The point of the book is to help Christian young people learn the basics of Christian holiness. If you are in a position where you want to help a person in such a situation, take a look.
