Hunger and thirst are energetic metaphors for passionate desire, and imply that righteousness is the true nourishment of the Spirit. Every longing of a noble spirit is blessed. Aspiration after the unreached is the salt of all lofty life. It is better to be conscious of want than to be content. There are hungers which are all unblessed, greedy appetites for the swine's husks, which are misery when unsatisfied, and disgust when satiated. But we are meant to be righteous, and shall not in vain desire to be so. God never sends mouths but He sends meat to fill them. Such longings prophesy their fruition.
Notice that this hunger follows the experience of the former Beatitudes. It is the issue of poverty of spirit and of that blessed sorrow. Observe, too, that the desire after, and not the possession or achievement of, righteousness is blessed. Is not this the first hint of the Christian teaching that we do not work out or win but receive it? God gives it. Our attitude towards that gift should be earnest longing. Such a blessed hungerer shall receive righteousness from the God of his salvation.' The certainty that he will do so rests at last on the faithfulness of God, who cannot but respond to all desires which He inspires. They are premonitions of His purposes, like rosy clouds that run before the chariot of the sunrise. The desire to be righteous is already righteousness in heart and will, and reveals the true bent of the soul. Its realisation in life is a question of time. The progressive fulfilment here points to completeness in heaven, when we shall behold His face in righteousness, and be satisfied when we awake in His likeness.
