Here is a beautiful quote from Pope Francis:
“Without grace we cannot take a step forward in Christian life. Everything is grace. It is not enough to accept the invitation to follow the Lord; one must be open to a journey of conversion, which changes the heart. The garment of mercy, which God offers us unceasingly, is the free gift of his love; it is precisely grace. And it demands to be welcomed with astonishment and joy: “Thank you, Lord, for having given me this gift.””
