Today we celebrate Pentecost, the birthday of the Church. It is now 50 days after Easter. The Apostles are hiding in the upper room and the Holy Spirit comes upon them. I guess you could say it was the wind of change - it was manifested immediately. From being afraid they went out to preach fearlessly. The amazing thing is that everyone understood what the Apostles had to say even though they spoke a different language.
When reading Acts one cannot help but be in awe of the details of the early Church. What an exciting history.
