"The Spirit of God is a spirit of peace. Even in the most serious faults He makes us feel a sorrow that is tranquil, humble, and confident. This is precisely because of His mercy. The spirit of the devil, instead, excites, exasperates, and makes us feel, in that very sorrow, anger against ourselves. We should, on the contrary, be charitable with ourselves first and foremost. Therefore if any thought agitates you, this agitation never comes from God, who gives you peace, being the Spirit of Peace, but from the devil." St.  Pio of Pietrelcina
