One of the greatest challenges of the Christian life is the pursuit of holiness. Christians tend to compartmentalize life, separating their devotion to God on a Sunday morning from every other facet of their lives. Jesus, however, calls the believer to an obedience that is radical, one that extends to every aspect of life. But what, exactly, does it mean to be holy? How is the Spirit at work within us to conform us to the image of Christ? What does it look like to be set apart, consecrated to God in a way that draws others to the holy God we worship? In this issue, pastors and theologians alike explore the diverse ways scripture describes holiness and the opposition every believer faces to the pursuit of a sanctified life.
