Because of sin we live in a broken and dysfunctional world. Global issues of poverty, hunger and malnutrition, homelessness, disease, violence, drug trafficking and abuse, and human trafficking face us at every turn. More than ever, there is the need for clarity on what the Bible says about justice. This six-week study looks at God's mandate to work for justice and mercy, with a focus on what Jesus says about this topic in the book of Luke. It addresses two main questions. First, what is justice? And, secondly, what is our obligation as Christians, both individually and corporately, to be persons of justice? The lessons for each week are divided into two parts: (1) personal study and reflection; and (2) group study.
