As the day of Pentecost arrived there was a buzz in the air. The city of Jerusalem was packed with pilgrims from all over the world, in the holy city to celebrate both the harvest gathered in and (by this time more importantly) the anniversary of the giving of the Law at Mount Sinai. But for the disciples, as they gathered together, there would have been other thoughts and emotions that day. They knew fear, puzzlement, perhaps impatience as they gathered to wait... for what? They knew the promises of Jesus but what that really meant in practical terms was still a mystery to them.
