When theologian Carl Trueman was recently asked “What are you learning about life and following Jesus?”, he answered “Life is short. Now in my mid-50s I am increasingly conscious that time is limited and that as a Christian I need to be very careful about my personal and professional priorities. Private time with family and close friends means so much to me these days. An evening in the company of loved ones is a precious gift that I have too seldom appreciated in the past. I am amazed at how many Christians spend their days on Twitter and Facebook—too often platforms for ephemeral trivia and unpleasantness. I do not believe Jesus wants me to use my remaining years in exchanging insults with other Christians. I think he wants all his people to witness to the world by using the time and talents he has given them to edify the body of Christ and to help the rising generation think clearly about the challenges we all face.” Thanks, Carl Trueman, for this timely challenge.
