We often realise our call in the world through our obedience. We become a physical expression of God’s call. Agnes Gonxha Bojaxhiu is best remembered for the work she led in the slums of Kolkata. However, initially principal of a Loreto Sisters school for girls, she was riding on a train from Kolkata to the Himalayan foothills for a retreat, when Christ called her to abandon teaching and work in the Kolkata slums serving the poorest and sickest.
