How to overcome satan

My morning meditations of late have been focusing on death and sin, Heaven and Hell.  Today's was on "How to Overcome satan".  I really thought these were good points to remember, so here is a synopsis on the ways to combat the devil:

If satan is a deceitful spirit, you must walk in truthfulness.

If he is the father of arrogance, you must walk in humility.

If he is the assassin of your neighbor, you must be charitable with all.

If he goes around furious and desperate, you must strive to serve God in peace, confidence and filial love.

If he cannot know or love God, you must strive to know and love God with all your being.

The remedy of remedies to overcome satan:

To love God with all your heart!
