Yet, even now, says the Lord, return to me with all your heart; rend your hearts and not your garments, and turn back to the Lord your God.
— Joel 2:12-13
“Return to me with all your heart” (Joel 2:12). To return to the Lord “with all [one’s] heart,” means taking the path of a conversion that is neither superficial nor transient, but is a spiritual journey that reaches the deepest place of our self. The heart, in fact, is the seat of our sentiments, the center in which our decisions and our attitudes mature.
— Pope Francis, Ash Wednesday 2015

This, rather, is the fasting that I wish:
releasing those bound unjustly,
untying the thongs of the yoke;
Setting free the oppressed,
breaking every yoke;
Sharing your bread with the hungry,
sheltering the oppressed and the homeless;
Clothing the naked when you see them,
and not turning your back on your own.
— Isaiah 58:6-7
Then your light shall break forth
like the dawn,
and your wound
shall quickly be healed;
Your vindication shall go before you,
and the glory of the LORD
shall be your rear guard.
Then you shall call,
and the LORD will answer,
you shall cry for help,
and he will say: Here I am!
— Isaiah 58:8-9a

The Spirit drove Jesus out into the desert,
and he remained in the desert for forty days,
tempted by Satan.
He was among wild beasts,
and the angels ministered to him.
— Mark 1:12-13
