A disciple of Jesus must become a student of Jesus in every conceivable fashion. As we are baptized into his death, we are raised into his life. As we are raised into his life, we are filled with his Spirit. As we are fi lled with his Spirit, we learn to think aft er his thoughts and to discern his mind to do the stuff of his work.In the Gospels, we see what it looks like when the Holy Spirit perfectly and completely inhabits, possesses, and empowers a human being in the midst of the fallen, broken world in which we live. Jesus does teach about the Holy Spirit, but far greater is the demonstration of the Spirit we witness through virtually every aspect of his life.In this daily devotional, J. D. Walt examines the shortest Gospel, Mark, and poses these questions: What might we learn about the person and work of the Holy Spirit through a close examination of the person and work of Jesus of Nazareth, the Messiah? And how might we proceed accordingly?
