Is this a "new" sort of spirituality?

 

No, and it is rooted in scripture, such as in the New Testament,

 

“Then I said, ‘Lo, I have come to do thy will, O God, as it is written of me in the roll of the book.’ When he said the above, ‘Thou hast neither desired nor taken pleasure in sacrifices and offerings and burnt offerings and sin offerings’ (these are offered according to the law), then he added, ‘Lo, I have come to do thy will.’ He abolishes the first in order to establish the second. And by that will we have been sanctified through the offering of the body of Jesus Christ once for all.” (Hebrews 10:7-10)

 

He wants us to remember and to pray for perseverance:

 

“For you have need of endurance, so that you may do the will of God and receive what is promised.”(Hebrews 10:36)

 

In the New Testament we find that it is the sole purpose of Our Divine Savior:

 

“And he who sent me is with me; he has not left me alone, for I always do what is pleasing to him.”(John 8:29)

 

“And going a little farther he fell on his face and prayed, My Father, if it be possible, let this cup pass from me; nevertheless, not as I will, but as thou wilt.” (Matthew 26:39)

 

He promises us something so profound:

 

“For whoever does the will of my Father in heaven is my brother, and sister, and mother.”(Matthew 12:50)

 

It is the sole purpose of Our Blessed Mother:

 

“Behold, the handmaid of the Lord, be it done unto Me according the Thy Word.”(Luke 1:38)
