Jesus came in the power of the Holy Spirit. He brought the God News of the Kingdom of God. We all like to hear good news. The Good News is about God's grace. His mercy and Love for us and that He is active in our lives today.
John announced the Messiah and called people to repent and turn to God and away from the world. Jesus baptism and anointing of the Holy Spirit began His ministry and reconciliation of the world and all those who believed in Him to God.
