The selection of writings by Charles de Foucauld, who was murdered in the Sahara in 1916, has lost none of its relevance even decades after its first publication. With the unwavering consistency of love, de Foucauld attempted to lead a life of poverty and humility, drawing from the situation in Nazareth and following in the footsteps of the incarnate Son of God. His notes and letters are organized around the fundamental themes of his thought, the mysteries from which he lived. These texts remain unchanged as a cohesive whole in the new edition, while the introduction has been updated and a current bibliography for German readers has been added.
