Continuing to explore that grace of the Spiritual Exercises’ Fourth Week, joy. Israel’s prophets were well-acquainted with it:
123. The prophets proclaimed the times of Jesus, in which we now live, as a revelation of joy. “Shout and sing for joy!” (Isaiah 12:6). “Get you up to a high mountain, O herald of good tidings to Zion; lift up your voice with strength, O herald of good tidings to Jerusalem!” (Isaiah 40:9). “Break forth, O mountains, into singing! For the Lord has comforted his people, and he will have compassion on his afflicted” (Isaiah 49:13). “Rejoice greatly, O daughter of Zion! Shout aloud, O daughter of Jerusalem! Behold, your king comes to you; triumphant and victorious is he” (Zechariah 9:9). Nor should we forget Nehemiah’s exhortation: “Do not be grieved, for the joy of the Lord is your strength!” (8:10).
These cited passages all land in the Advent season, though Isaiah 12 is one of the “psalms” for the Easter Vigil.
