Gordon Brownville's Symbols of the Holy Spirit tells about the great Norwegian explorer Ronald Amundsen, the first to discover the magnetic meridian of the North Pole and to discover the South Pole. On one of his trips, Amundsen took a homing pigeon with him. When he had finally reached the top of the world, he opened the bird's cage and set it free. Imagine the delight of Amundsen's wife, back in Norway, when she looked up from the doorway of her home and saw the pigeon circling in the sky above. No doubt she exclaimed, "He's alive! My husband is still alive!"
So it was when Jesus ascended. He was gone, but the disciples clung to his promise to send them the Holy Spirit. What joy, then, when the dove-like Holy Spirit descended at Pentecost. The disciples had with them the continual reminder that Jesus was alive and victorious at the right of the Father. This continues to be the Spirit's message.
