All three readings for the 20th Sunday in Ordinary Time celebrate the power of God to change human hearts.
The selections begin with Jeremiah's complaint against God, alleging that God deceived him and also that Jeremiah let himself be deceived. Several chapters earlier he stated, "When I found your words, I devoured them; they became my joy and the happiness of my heart, because I bore your name, O Lord, of hosts. ... Under the weight of your hand I sat alone because you filled me with indignation."
