Today we celebrate Pentecost, a.k.a. The Church’s Birthday.
For nine days after Jesus’s ascension, the eleven remaining apostles, Mary, and a few others were gathered in the Upper Room.
As Jesus promised (Luke 24:46-49) the Holy Spirit descended upon them.
Tongues of fire appeared above their heads enabling them to speak in different languages. They were ready to fulfill the great commission (Acts 2:2-4).
Peter, inspired by the Holy Spirit, preached his first sermon. It “cut them to the heart”and around 3,000 people were converted (Acts 2:38-41).
This was the birth of the Church, and Christianity began to quickly spread to all nations.
