When the angels announced the good news to the shepherds the men took action. They went to Bethlehem to see the Christ-child for themselves. Supposing they simply sat around discussing the brightness of the angelic appearance and the wonder of the message. Then, some 40 years later, one of the shepherds tells his small grandson about that eventful night. I never went to see.
Many people are like that shepherd.
They have heard moving sermons about Jesus. Jesus asks his disciples a more penetrating question. Everywhere the gospel has ever been preached persons are called upon to make a decision about the identity of Jesus Christ. Jesus' times were no different from our times. In any age, even in our age, where at times we have more questions than answers, we are still called upon to answer the paramount question.
