Father, You endowed John of the Cross with a spirit of self-denial and a love of the cross. By following his example, may we come to the eternal vision of Your glory.
THE best exposition on the spiritual life --that is, in my estimation there is no other work that captures the essence of the various gifts of the Holy Spirit with regard to the spiritual life-- is the book Christian Spirituality by Dominican Father Jordan Aumann (1916-2007). Regrettably, I think the book is out of print and old copies tend to be expensive but you may search for an online copy of it. If you get a copy, don't let it out of your sight! Nevertheless, Father Jordan's thoughts on Saint John of the Cross easily expose the greatness of today's saint.
