"The first condition necessary for victory over evil is active cooperation in the work of Christ in union with our brethren. The second condition is vigilance. Jesus warns us that the enemy of good is lying in wait. Even after he leaves a soul, he is ready to return, more powerful than before, "with seven other spirits more wicked than himself" if he finds the soul empty and open to his snares. To halt the approach of evil we must watch in prayer, filling our heart with God so that there will be no place in it for the enemy. And there is no place when the soul is wholly united to God through the acceptance and observance of His word, of His will…" Divine Intimacy
