Today is the feast day of St. Matthias. He was chosen to replace Judas after the ascension of our Lord. We don't know a lot about him, but he was numbered with the apostles and preached the Gospel in other places just as the rest of the apostles did.
Matthias is probably not a name that is familiar to all. He certainly does not have the prestige of Peter, James, John, or even Paul. But he labored faithfully. Through his efforts many lives were touched. Joined collectively with the other apostles, he changed the world forever by his faithfulness to tell others about Jesus even to death.
For a great portion of my life I have been convinced that if I am going to do anything significant for the Lord, it will need to be on a grand scale. But St. Matthias shows me that it isn't necessarily true. He labored in relative obscurity, but he made a great difference. I want to imitate him in this. I want to be faithful to God's call regardless of how great or small.
I may not be able to change the world, but I hope I can make a difference in my small part of it. And in the grand scheme of things, as my minute contribution is joined with so many others, we really are changing the world.
