The work of devils and of darkness is never more certain to be defeated

The work of devils and of darkness is never more certain to be defeated than when men and women, not finding it easy or pleasant but still determined to do the Father’s will, look out upon their lives from which it may seem every trace of God has vanished, and asking why they have been so forsaken, still bow their heads and obey.
