Tanquerey paints a vivid ideal for moral virtue. Climbing a trenchant divide is what we actually live. On the one hand, we are encouraged by the good fight. On the other is the promise of great grace waiting to be poured upon those who wait in the stillness.
I would say, out of constancy, only to pray. Pray to be still. Pray to act. Pray to hope.
A white martyrdom helps no one if it is done with anger. Therefore, pray and hope.
