I've just finished reading a terrific book, My Life with the Saints, by James Martin. It is a sort of memoir, relating different periods of his life to different saints. One of the clear messages of the book is that God calls all of us to be saints. No matter what our limitations, no matter what our circumstances, God wants to make each one of us saints.
God is not calling us to be St. Joan of Arc or St. Francis of Assisi. God made each of us different, with a unique set of gifts and talents. God will make each of us saints in our own peculiar way. Thomas Merton said, "For me to be a saint means to be myself." God wants to make me all that God created me to be. Mother Teresa of Calcutta said, "You can do something I can't do. I can do something you can't do. Together let us do something beautiful for God."
To want to be a saint, then, is not pride. It is to want what God wants for me. Merton quotes a friend as saying, "All that is necessary to be a saint is to want to be one. Don't you believe God will make you what He created you to be, if you consent to let Him do it? All you have to do is desire it." I do desire it.
