Thomas a' Kempis
The Voice of Christ: “All is not lost, then, if you sometimes feel less devout than you wish toward Me or My saints. That good and sweet feeling which you sometimes have is the effect of present grace and a certain foretaste of your heavenly home. You must not lean upon it too much, because it comes and goes. But to fight against evil thoughts which attack you is a sign of virtue and great merit. Do not, therefore, let strange fantasies disturb you, no matter what they concern. Hold strongly to your resolution and keep a right intention to God.”
