The book in its first chapter refers to the living and indubitable presence of Christ: The resurrection of Christ is the cornerstone of Christianity and the event that begins the book of events. The kingdom of God, the divine government in the hearts, lives and the kingdom of God through the power of the Spirit, and here is close to transfer that power and responsibility to his disciples, baptizing them with the same Spirit that prepared him for his ministry .
Verse 1.5 refers to "you will be baptized with the Holy Spirit" is the origin of the phrase "baptism or with the Holy Spirit", Many interpret this as something other than conversion, which seems to be referred to in 1 Corinthians 12.3 , where the Holy Spirit is the agent that performs the baptism.
Jesus also corrects the false conception of the disciples and adjusts their perspective on the kingdom of God. He tells them that the kingdom is spiritual in character, international in its membership and gradual in its expansion. "Upon you the Holy Spirit" is a very important concept in Luke and the Acts; and Jesus is the first example of the work of the Holy Spirit in and about us.
