“I am the light of the world,” he says in John 8:12. “Whoever follows me will never walk in darkness, but will have the light of life.” To Simon and Andrew fishing, to James and John, to Matthew collecting taxes, he called out: “Follow me!” They obeyed, literally leaving what they were doing to be with him. In this way they learned by observation and direct contact and involvement to do what he did and be as he was. It may have been hard, but a least it was clear-cut and simple.
