Isaiah 42:1 “Behold! My Servant whom I uphold, My Elect One in whom My soul delights! I have put My Spirit upon Him; He will bring forth justice to the Gentiles.
These word are description about Jesus Christ, Messiah and King! The one and only chosen directly by God.
Our Lord would have the Holy Spirit, given visibly when Christ was baptised by John.
God’s task for Christ was to bring justice to all the people in the land who were willing and able to accept His Words.
This alone gave Him to qualifications as teacher and King.
