Their voice has gone forth to all the earth, and their words to the ends of the world.
Andrew was one of the first to be chosen to be a follower of Jesus in a long line of followers. When Jesus said come, follow me he went right away. Basically he answered yes at the moment he was asked. He didn't wait a few days or months, but at that moment.
They took up the call to preach the good news to all the earth, to bring men to salvation. What a gift St. Andrew was given to go out to all the world to give us Jesus.
When we hear the word of God do we go out and speak of him too? Do we mention what good he does in our life so others may come to know and love him. He's awesome, can't live without him.
