This is literally an invitation presented in gold leafing and calligraphy, calling you to consider whether or not God may be calling you to religious life.
For the religious who has made public vows of chastity, poverty and obedience, there is a strange wedding of the soul to God that renders ALL acts done in religious obedience, even the tiniest (like getting out of bed at the first sound of the alarm/bell or even just making your bed before you go about the business of your day) to be acts of divine worship. By getting out of bed, even if all you’re thinking about in that first moment is “my head hurts” – you are worshipping God! HOW AWESOME IS THAT??!!
If you’re discerning, consider taking a leap of faith. If it is true that He is calling you, how could you possibly pass up this mystical means of making your entire life a prayer?
