Adrienne von Speyr, whom Hans Urs von Balthasar credits with having an incalculable influence on his own writing, examines the mission of thirty-four figures in salvation history, from Abraham, through Moses, David, Elijah, and Isaiah, to the New Testament era and Our Lady. Mission is central to Christian life, and if we are to do justice to what God chooses for us, we can profit from looking at the chosen ones in scripture and seeing how they accepted their callings and lived out a life of service. Adrienne's contemplation on these unique missions helps us to open ourselves and respond to the call of God in our own lives.
