James Martin, SJ, wrote this in an article for Loyola Press:

The beginning of sanctity is living yourself as a creation of God. And that means all of yourself, even the parts of you that you wish weren’t there, the parts of you that you wish God hadn’t made, the parts of you that you lament, … those very weakness are the most important paths to holiness, because they remind you of your reliance on God.

We tend to think of holiness as something that can be achieved only by people like Mother Teresa or St. John XXIII—not something that can be achieved by “ordinary people,” as, for instance, us. And yet most people know others they consider holy—good people. A next-door neighbor, or an always-reliable friend, or the doctor who always listens, or … well, you know. Ordinary people. People you want to be like.

And so we sing, “Here I am, Lord, I come to do your will” (Psalm 40), knowing that we’re not perfect, but we are trying. David Haas’s “You Are Mine” sings God’s love for us ordinary, imperfect folks, made whole and holy by God’s presence in us. And don’t forget Bob Dufford’s “Behold the Lamb of God,” which expands on John the Baptizer’s recognition of Jesus, upon whom God’s Spirit rests—the same Spirit that energizes us and gives us the strength to do what God wants of us.
