The "Our Father" is not a method of prayer-which one might expect in response to a question regarding how to pray. The "Our Father" focuses and wisely orders the deep desires of our heart, the cry of the heart of those who wish to engage their Lord intimately.
And, amazingly, the response to our deepest desires, to the cry of our heart is the Holy Spirit. It does not sound very romantic, does it? The One who, according to St. Thomas Aquinas (Summa Theologica, I, Q. 38, art. 1 & 2; II, II, Q. 38, art 9, obj. 3), is the "Gift" is beyond romantic, and uniquely full-fills the heart, enabling us to engage our Lord intimately. This is good news. This is, well, a gift. Amen. Alleluia.
Yours in our Lord,
