How important was the indwelling presence of the Holy Spirit in Jesus’ life? I think that P.C. Nelson summed it up the best when he wrote …

“Of all the Old Testament prophecies concerning the Messiah, the one
which Jesus pointed out in His home synagogue when He returned
to Nazareth was the one in Isaiah 61: 1, 2, concerning His anointing
with the Spirit. “The Spirit of the Lord is upon me, because he hath
anointed me to preach the gospel to the poor; he hath sent me to heal
the broken hearted, to preach deliverance to the captives, and
recovering of sight to the blind, to set at liberty them that are
bruised, to preach the acceptable year of the Lord.” (Lu. 4: 18, 19.)”
~ P.C. Nelson “The Baptism in the Holy Spirit”

Enough said.
