The Book of Matthew 5:15 in the Christian Bible entreats the faithful to realize, “You are the light of the world” and, just as no one would light a lamp and hide it under a basket, you should similarly “let your light shine.” The popular gospel song, “This Little Light of Mine,” urges us to heed that exhortation. But what does it mean to “be the light? How do we make that light shine? Mike Holliday, will explore those questions with us.
