God's work of Restoration is a work of the Holy spirit in and through the lives of those who have Believed in Jesus and have been born from above. (john 3:3). The prophet Joel foretold a day when god would pour out his spirit "on all flesh"
(Joel 2:28,29). Thus, His Power would be shared with all his people and not limited to one chosen individual.
This Explains Why Christ told his disciples it was to their advantage for him to leave them and go to the father. (john 16:7)
because then the spirit could be sent to indwell each of them, to fill them and to enable the supernatural works of god to be done through them.
Titus 3:5,6 Revels that even salvation - the re generation of the dead spirit of man and the cleansing that make the new man acceptable to god - is the work of the holy spirit.
Finally in acts 1:8 Jesus tells the disciples to do nothing until the Holy Spirit has come. Then he promises they will be empowered to witness of him and their witness will spread the good news throughout the world.
