The renunciation of marriage and family is thus to be understood in terms of this vision: I renounce what, humanly speaking, is not only the most normal but also the most important thing. I forgo bringing forth further life on the tree of life, and I live in the faith that my land is really God - and so I make it easier for others, also, to believe that there is a kingdom of heaven. I bear witness to Jesus Christ, to the Gospel, not only with words, but also with this specific mode of existence, and I place my life in this form at his disposal.
