“Stand up and go; your faith has saved you.” Jesus speaks these words to the ten lepers in today's gospel (Lk 17:19). Pope Benedict XVI commented on them at the Twentieth World Day of the Sick, on February 11, 2012:

The encounter of Jesus with the ten lepers, narrated by the Gospel of Saint Luke (cf. Lk 17:11-19), and in particular the words that the Lord addresses to one of them, “Stand up and go; your faith has saved you” (v. 19), help us to become aware of the importance of faith for those who, burdened by suffering and illness, draw near to the Lord. In their encounter with him they can truly experience that he who believes is never alone! God, indeed, in his Son, does not abandon us to our anguish and sufferings, but is close to us, helps us to bear them, and wishes to heal us in the depths of our hearts (cf. Mk 2:1-12).

The faith of the lone leper who, on seeing that he was healed, full of amazement and joy, and unlike the others, immediately went back to Jesus to express his gratitude, enables us to perceive that reacquired health is a sign of something more precious than mere physical healing, it is a sign of the salvation that God gives us through Christ; it finds expression in the words of Jesus: your faith has saved you. He who in suffering and illness prays to the Lord is certain that God’s love will never abandon him, and also that the love of the Church, the extension in time of the Lord’s saving work, will never fail. Physical healing, an outward expression of the deepest salvation, thus reveals the importance that man – in his entirety of soul and body – has for the Lord.

The story of Jesus's healing the leper in today's Gospel (Mark 1: 40-45) is a source of great hope for us all. Paschasius Radbertus (785–865), the Benedictine abbot and theologian, encourages us to trust in God's mercy and forgiveness:

However great our sinfulness, each one of us can be healed by God every day. We have only to worship him with humility and love, and wherever we are to say with faith: Lord, if you want to you can make me clean. It is by believing from the heart that we are justified, so we must make our petitions with the utmost confidence, and that the slightest doubt of God’s power.

If we pray with a faith springing from love, God’s will need be in no doubt. He will be ready and able to save us by an all-powerful command. He immediately answered the leper’s request, saying: I do want to. Indeed, no sooner had the leper begun to pray with faith than the Savior’s hand began to cure from his leprosy.
