Ascension Day (Acts 1)

If you follow the church calendar a bit, you may have noticed that last Thursday was a memorable day. In some countries it is actually a holiday where we commemorate the Ascension of the Lord into Heaven. Now, in between Easter and Pentecost (not to mention Christmas), Ascension day may not make it into your top three Christian holidays. And so I wanted to talk about this event using three questions: 1) What happened? 2) How can we be sure that it happened? And 3) What is the significance for us?
