The readings for the 26th Sunday in Ordinary Time focus on the unseen and hidden areas of our hearts in which God actively works with the power of His word.
In the first reading, God articulates what is happening in the heart of the Jewish followers: "You say, 'The Lord's way is not fair!'" Thus, God surfaces the hidden attitudes of people called to follow His way to freedom. In effect, He answers by suggesting that His ways are fair and just, but their behavior isn't.
