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.
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.
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.
