Prayer

"As He was praying alone, the disciples were with him" (Luke 9:18)

'The disciples are drawn into His solitude, His communion with the Father that is reserved for Him alone.  They are privileged to see Him as the One Who speaks face to face with the Father, person to person.  They are privileged to see Him in His unique filial being---at the point from which all His words, His deeds, and His powers issue...This seeing is the well-spring of their faith, their confession; it provides the foundations of the Church.' (Benedict XVI--Jesus of Nazareth)

To be given the Holy Spirit is to enter into Jesus' own relationship with the Father.
