I've started reading my third book by Fr. Benedict Groeschel titled Travelers Along the Way, in which he wrote about 30+ men and women who shaped his life. One of them was none other than Mother Teresa. Fr. Groeschel was at the time the liaison between Mother and the New York archdiocese in which some houses were opened for her Missionaries of Charity. Once when Fr. Groeschel felt discouraged that he couldn't handle what he was told to do well enough and thought of resigning his post, Mother Teresa asked him pointedly why he thought God had chosen him to be a priest. Father had trouble coming up with a right answer and Mother Teresa looked at him and said, "You are chosen because of the humility of God. God chooses the weakest and the poorest, the most inappropriate persons to use." She followed up with what Fr. Groeschel considered to be extremely revealing, something he would never forget: "I pray that my place will be taken by the most unattractive and ungifted of all the sisters. Then everyone will know that this is not our work but God's work. Don't ever forget that you are chosen by the humility of God." [I hope that Fr. Groeschel wouldn't mind my quoting these sayings directly from his book.]
It's true that the Holy Mother appeared to the poor and uneducated rather than the strong, rich, wise or gifted. And Jesus called a bunch of fishermen, not any learned scholars, to follow him. The lesson here is that when we are called to serve the Lord in whatever way, we should realize that God has chosen us, no matter how inadequate we might feel. It's an honor and the Lord knows exactly what he is doing.
