Fidelity must be unblemished as gold high heat

Nov. 14
What you should do now that Jesus for His goodness wants to test your loyalty is always solicitous to show compliance with your homework and do not neglect anything you usually practice in times of comfort and prosperity, without stopping to think sensitive taste do not feel, as this is something accidental, which often can also be harmful to the soul. Serving God without testing it on some comfort sensitive part is what constitutes substantial and true devotion. This is what it means to serve God and love for love itself.
Until the soul comes to acquire this substantial devotion, your situation is very dangerous and needs to proceed with great discretion and foresight.
(July 14, 1914, to Raffaelina Cerase - Letters. II, p. 126)
