As we celebrate the birth of the Protestant Reformation, 500 years ago this fall, that we will meditate on Galatians, which Luther called “my Katie von Bora,” in six Morning Devotions over the semester. In the first-century churches in Galatia, Paul saw symptoms of spiritual dehydration—that they were “thirsty for grace.”—The Reformers encountered the same symtoms in the 16th century, and they afflict many Christians today. When we display pride, fear of man, hypocrisy, competitive conflict, and joyless slavery, the diagnosis is spiritual dehydration; and the treatment is God’s lavish grace in Christ.
