Act Justly is the final book in the trilogy begun by Walk Humbly and Love Mercy, together forming an introduction to Christian faith and life. Taking their inspiration from a question posed in the Old Testament, 'What does the Lord require of you? To act justly and to love mercy and to walk humbly with your God', each book in the series offers a practical ethic for living that is rooted in timeless wisdom.

Focusing on two of the most outstanding justice issues of our day - racial and climate injustice - as well as individual stories of injustice, Act Justly offers practical ways of thinking about justice and cultivating habits of justice to foster the life of God, so that injustice can be challenged and the world can be changed.
