To hunger and thirst for righteousness is to zealously desire to know what is right. What you do and how you act are important to God. We are called to do what is right—not just what is expedient. We see a pattern in the beatitudes. They come in pairs. We mourn while we are learning to be poor in spirit, and when we become meek, we will hunger and thirst for righteousness. The promise is we will be filled completely.
