November 8

You must direct you wrath only against the demons, for they wage war upon us through our thoughts and are full of anger against us. As regards the manner of the hourly warfare within us, listen and act accordingly. Combine prayer with inner watchfulness, for watchfulness purifies prayer, while prayer purifies watchfulness. It is through unceasing watchfulness that we can perceive what is entering into us and can to some extent close the door against it, calling upon our Lord Jesus Christ to repel our malevolent adversaries. Attentiveness obstructs the demons by rebutting them; and Jesus, when invoked, disperses them together with all their fantasies.

The blessed remembrance of God–which is the very presence of Jesus–with a heart full of wrath and a saving animosity against the demons, dissolves all trickeries of thought, plots, argumentation, fantasies, obscure conjectures and, in short, everything with which the destroyer arms himself and which he insolently deploys in his attempt to swallow our souls. When Jesus is invoked, He promptly burns up everything. For our salvation lies in Christ Jesus alone. The Savior Himself made this clear when He said; ‘Without Me you can do nothing’ (John 15:5).
