From the Lenten Message of Pope Francis, 2015.
As a way of overcoming indifference and our pretensions to self-sufficiency, I would invite everyone to live this Lent as an opportunity for engaging in what Benedict XVI called a formation of the heart (cf. Deus Caritas Est, 31). A merciful heart does not mean a weak heart. Anyone who wishes to be merciful must have a strong and steadfast heart, closed to the tempter but open to God. A heart which lets itself be pierced by the Spirit so as to bring love along the roads that lead to our brothers and sisters. And, ultimately, a poor heart, one which realizes its own poverty and gives itself freely for others.
During this Lent, then, brothers and sisters, let us all ask the Lord: “Fac cor nostrum secundum cor tuum”: Make our hearts like yours (Litany of the Sacred Heart of Jesus). In this way we will receive a heart which is firm and merciful, attentive and generous, a heart which is not closed, indifferent or prey to the globalization of indifference.
