After the death of Jesus, the Disciples locked themselves in a room for fear of what might befall them in the world outside. While it was safe and comfortable being together, it was not what Jesus wanted of them.
At the first Pentecost, they were filled with the Spirit and commissioned to go out to all the world and spread the Gospel.
How comfortable and safe it is for us to practice our Faith within the confines of our own Church. We can be tireless workers for our Pastors and Priests but often we deliberately shy away from situations that might involve us having to be a Christian in a non-Christian environment.
Just as the Disciples were sent out into the world, so must we all accept our responsibility as Christians to follow in their footsteps.
They were not told how to spread the Good News. Like us, they were all given different gifts that enabled them to perform their mission in their individual ways.
We are not all called to stand on street corners and preach, but we are called to take the Gospel to one another. The same Spirit who gave power to the apostles will assist each one of us with the way we perform this task we have been given.
