Listen to this invitation

Wash yourselves clean!
Put away your misdeeds from before my eyes;
cease doing evil; learn to do good.
Make justice your aim: redress the wronged,
hear the orphan’s plea, defend the widow.

Come now, let us set things right,
says the LORD:
Though your sins be like scarlet,
they may become white as snow;
Though they be crimson red,
they may become white as wool.
(from today's first reading - Isaiah 1:10, 16-20)
