I delight to do Thy will, O my God: yea, thy law is within my heart.  (Ps. 40:8)

Whosoever shall do the will of God, the same is My brother, and my sister, and mother. (Mark 3:35) 

Plunge with eyes closed into the sea of Divine providence and benevolence; let the mighty waves of God’s will carry you, like some inanimate thing, with your own will unresisting, thus quickly to be borne to the harbor of salvation and Christian perfection (Unseen Warfare) 

As all your treasure is in your heart and your will, and God asks of you your heart, saying, My son, give me thine heart, therefore, in order to fulfill God’s perfect will, renounce your own corrupt, wayward, plausible will, and know it not; know only God’s will. Not my will, but Thine be done. –St. John of Kronstadt

     ..as long as your selfish will rules, you cannot pray to the Lord with a pure heart: Thy will be done. If you cannot get rid of your own greatness, neither can you lay yourself open for real greatness. If you cling to your own freedom, you cannot share in true freedom, where only one will reigns. Tito Colliander, The Way of the Ascetics
