My mother and her sisters engage in what is increasingly becoming a lost art form—writing letters. Each week they pen personal words to each other with such consistency that one of their mail-carriers worries when he doesn’t have something to deliver! Their letters brim with the stuff of life, the joys and heartaches along with the daily happenings of friends and family. I love to reflect on this weekly exercise of the women in my family. It helps me appreciate even more the apostle Paul’s words that those who follow Jesus are “a letter from Christ,” who were “written not with ink but with the Spirit of the living God” (2 Cor. 3:3). In response to false teachers who wanted to discredit his message (see 2 Cor. 11), Paul encouraged the church in Corinth to keep on following the true and living God as he had previously taught.
