28 Should you encounter fresh contradictions and fresh signs of hostility on the road, do not allow yourselves to be cast down; for the righteousness of your cause will become clearer day by day for the very reason that your adversaries will be compelled, in order to meet you, to have recourse to similar weapons, whilst the trials you will have to suffer will increase your merit in the eyes of all good men, and what is much more important, before God.
