Shellberg traces how the stories of Jesus' cleansing of leprous bodies in the Gospel become the pattern for the divine cleansing of Gentile hearts throughout Acts, and one of Luke's primary expressions of the means of God's salvation and favor through the dissolving of distinctions between Jew and Gentile.
