Blessed are they that hunger and thirst after righteousness: for they shall be filled.' Not only do the followers of Jesus renounce their rights, they renounce their own righteousness too. They get no praise for their achievements or sacrifices. They cannot have righteousness except by hungering and thirsting for it (this applies equally to their own righteousness and to the righteousness of God on Earth), always they look forward to the future righteousness of God, but they cannot establish it for themselves. Those who follow Jesus grow hungry and thirsty on the way.
