You may recall the two-note whistle signal on a Navy ship just before the announcement on the loud speaker: "All hands on deck! All hands on deck!" All sailors then scramble to their assigned positions and prepare to do whatever is necessary. In times of war, it often means direct contact with the enemy.
Joel 2's trumpet blast is God's all-hands-on-deck call to action. This edition focuses on how women have answered that call in the Lake Union.
