By James T. Majewski, Catholic Culture - If with the first three chapters, St. Alphonsus makes the case for obedience to God—the excellence of this virtue, and that man’s ultimate happiness derives from it—in these chapters, St. Alphonsus gets practical, turning his attention to those instances where obedience to God can sometimes be especially difficult... In particular, he focuses on our susceptibility to sickness, and stresses the importance of obedience to God’s will in times of infirmity.
