The first-fruit of the Spirit is peace and joy. Because then the holy Virgin had drunk in all the graces of the Spirit, she rightly adds, And my spirit hath leaped for joy. (exultavit.) She means the same thing, soul and spirit. But the frequent mention of leaping for joy in the Scriptures implies a certain bright and cheerful state of mind in those who are worthy. Hence the Virgin exults in the Lord with an unspeakable springing (and bounding) of the heart for joy, and in the breaking forth into utterance of a noble affection. It follows, in God my Saviour.
