Delivered by the Gospel into the Kingdom

In vs 42 the people sought him and tried to keep him from leaving, and Jesus is being pressed upon by everyone for His miracle's and healing's. But His response to everyone is very profound for it is going to define the scope and purpose of His earthly ministry and the Ministry of His Disciples until He set's a new mandate to His people.
Jesus say's "I MUST"- which is a term used for the inevitiblity of an event. This is not only speaking of the necessity of the event, but of the events predestined infatic outcome.
He said "I Must Preach" it is infatically necessary as an predestined decree that I am going to euangelion- to preach- to proclaim.
The preaching is specific to the purpose for which Jesus came, which He continues to define,as He says.
I must preach the "Good News" generally this is speaking of announcing a good report, such as Luke 1:19; Revelation 14:6.
However the specific Good News that Jesus was sent to preach is an eternally devine foreordained, promised, covenented, Good News that is the divine message of salvation.
This is the first fruit of the "Good News" that it must be preached, for it is that gospel milk which spiritually nurishes all those which aquire it.
Jesus is interested in the precise "Good News" which is specific to the Kingdom of God. The people wanted the manifestation of his power, they wanted to see and expierence healing power, which they had never seen before. The Gospel starts with the nature of God, His attributes. God is holy. Lev 11:44-45.If God judges you on the day of Judgment will you be innocent or Guilty? If you are guilty, would it be right Just and Good of God to let you go? God will uphold His justice.
