Since our commitments and our worries keep us living the same routine, putting us at risk of forgetting just how extraordinary this adventure is that Christ has involved us in, we need to begin again each day with the demanding itinerary of evangelical life, retreating within ourselves through moments of reflection that regenerate our spirit. With the ancient ritual of the imposition of the ashes, the Church introduces Lent as a spiritual retreat that lasts 40 days.
In this way we enter into the atmosphere of Lent, which helps us rediscover the gift of faith received at baptism and which encourages us to approach the sacrament of reconciliation, placing our commitment to conversion under the symbol of divine mercy. . . .

Upon placing ashes on the faithful, the celebrant says: "Remember that you are dust and to dust you shall return" (cf. Genesis 3:19), or he repeats Jesus' exhortation: "Convert and believe in the Gospel" (cf. Mark 1:15). Both practices recall the truth of human existence: We are limited creatures, sinners constantly in need of penitence and conversion. How important it is in our day and age to listen and welcome such a call! When proclaiming his independence from God, the contemporary man becomes his own slave and often finds himself inconsolably alone. The invitation to convert is therefore a spur to return to the arms of God, caring and merciful Father, to trust him, to entrust oneself to him like adopted children, regenerated by his love.
Teaching with wisdom the Church reiterates that conversion is above all a grace, a gift that opens the heart to God's infinite love. Through his grace he anticipates our desire for conversion and supports our efforts toward full adherence to his saving will. To convert means to let Jesus win our hearts (cf. Philippians 3:12) and "to return" with him to the Father.
Conversion therefore means to give oneself to the teachings of Jesus and to obediently follow in his footprints. . . .
The Lenten walk to conversion, which we undertake today with the whole Church, becomes the propitious occasion, "the favorable moment" (cf. 2 Corinthians 6:2) to yield ourselves once again to the hands of God and to practice what Jesus continuously repeats to us: "If someone wants to follow me he must renounce himself, take up his cross and follow me" (Mark 8:34), and thus take the path of love and true happiness.
