He orders us what we must do next, and says, "Go forth" if you have
fulfilled the first necessary condition--that is to say, if you see
in grace and in charity, and if you have well observed your model,
Christ, in His "going forth"; there leaps up in you, from your love
and loving observation of your Bridegroom, an ardour of justice--
that is to say, a desire to follow Him in virtue. Then Christ says
in you, "Go forth." This going forth must have three modes. We must
go forth towards God, towards ourselves, and towards our neighbour
by charity and justice; for charity always pushes upward, towards
the kingdom of God, which is God Himself; for He is the source from
which it flowed without any intermediary, and He remains always
immanent in it. The justice which is born of charity wishes to
perfect the manners and the virtues which are suitable to the
kingdom of God--that is to say, to the soul. These two things,
charity and justice, establish a solid foundation in the kingdom of
the soul where God may dwell, and this foundation is humility. These
three virtues support all the weight and all the edifice of all the
virtues and all sublimity; for charity maintains man in presence of
the unfathomable good things of God from whence it flows, so that it
perseveres in God, and increases in all the virtues and in true
humility; and justice maintains man in presence of the eternal truth
of God, so that truth may be discovered by him, and that he may be
illuminated, and may accomplish all the virtues without error. But
humility maintains man always before the supreme power of God, so
that he remains always abased and little, and abandons himself to
God, and holds no longer by himself. This is the way in which a man
must bear himself before God, that he may grow alway in new virtues.

HOW HUMILITY IS THE FOUNDATION OF ALL THE VIRTUES
