With the bestsellers "Prickly Personalities" and "My Thorns," readers have already immersed themselves in the profound world of thorns. Now, Jörg Berger presents a workbook on the topic, featuring the following contents: - Profiles of "Difficult Personalities" - Questionnaires for self-exploration - Worksheets: Dealing with Difficult Personalities - Profiles of "My Weaknesses" - Worksheets: "Overcoming Personal Weaknesses" - 8 units for thematic discussion groups "Dealing with Difficult People" - 8 units for Bible study groups "How Does Jesus Deal with Difficult People?" - 9 units "From Personal Weaknesses to Personal Development." Further chapters provide information on how the materials can be used for self-study, one-on-one exchanges, discussion or Bible groups, and for application in seminars. An invitation to do so.
