Chapter 24 — Part II — The Beatitudes

Section 457. Q. Who are they that hunger and thirst after righteousness? A. They who, while they love to do good, yet count not themselves righteous, nor rest on their own good works, but acknowledge themselves sinners, and guilty before God; and who, by the wish and prayer of faith, hunger and thirst after the justification of grace through Jesus Christ, as after spiritual meat and drink.
