"Valiantly
fight temptations like strong souls, and fight along wit the Supreme
Chief. When you fall, do not stay there prostrated in body and spirit.
Humble yourself greatly but without being discouraged. Lower yourself
without degrading yourself. Wash your imperfections and falls with
sincere tears of contrition, without lacking trust in divine goodness,
which will always be greater than your ingratitude. Propose to make
amends without being presumptuous, but your strength must be in God
alone. Finally, confess sincerely that if God were not your breast-plate
and shield, you would be imprudently pierced with every kind of sin."
- Letters III, p. 702
