Blessed are those who hunger and thirst for righteousness? What is righteousness? We mourn evil and desire justice. When we don’t mourn for our own sins we become arrogant and self-righteous instead of humble. Mourning for sin means we sincerely pray, “thy will be done on earth as it is in heaven,” we are praying for God’s righteousness on earth. Some argue that it is impossible for human thoughts to attain this high standard completely and they are probably correct. Yet, the Holy Spirit patiently works with us and pricks our consciences to do right. Jesus’ promise is that if we crave justice and what is right, we will be filled.
