The whole scene at Jesus’ baptism is an initiating event. Things would never return to normal for Jesus. Immediately He is led by Holy Spirit into the wilderness where there would be fasting and extreme temptation for forty days. Once, the desert battle was won Jesus returned and began to preach around the countryside.

Luke 4:
14 Jesus returned to Galilee in the power of the Spirit, and news about him spread through the whole countryside. 15 He was teaching in their synagogues, and everyone praised him.

This was not just the local carpenter expressing opinions about religion. Some would dismiss him in that way. He begins to function as a Rabbi and a prophet and people would recognize another power at work. Jesus now spoke and acted in the power of Holy Spirit.

Luke 4:
16 He went to Nazareth, where he had been brought up, and on the Sabbath day he went into the synagogue, as was his custom. He stood up to read, 
17 and the scroll of the prophet Isaiah was handed to him. Unrolling it, he found the place where it is written:
18 “The Spirit of the Lord is on me,
    because he has anointed me
    to proclaim good news to the poor.
He has sent me to proclaim freedom for the prisoners
    and recovery of sight for the blind,
to set the oppressed free,
19     to proclaim the year of the Lord’s favor.”

Why was the Holy Spirit coming to dwell with Jesus? Heaven’s mission must now be accomplished and spoken of with a new apologetic. The old ways of saying things were dying in the ears of the nation. God’s message could not be told unless the Spirit came upon Jesus to mark Him for this purpose.

How could anyone hear unless God empowered someone to speak up? The agenda of Heaven was now to be proclaimed. Good news for the poor rhymed with freedom for prisoners. Healing and deliverance freely available to all—this marked the time of God’s coming favor upon the world.
