Scripture says that ...
Jesus was NOT going around being "fully God" and able to do everything himself.
Even though Jesus, the man, had God * within him,
He still was a man and needed a lot of help from the Father and the Holy Spirit.
* It's my understanding that he had the Second Person of the Triune God within Him.
Luke 4:18
The Spirit of the LORD is upon Me, because He has anointed Me to preach the gospel to the poor;
He has sent Me to heal the brokenhearted, to proclaim liberty to the captives (of Satan)
and recovery of sight to the blind, to set at liberty those who are oppressed (by demons)
Luke 5:17
Now it happened on a certain day, as He (Jesus) was teaching,
that there were Pharisees and teachers of the law sitting by,
who had come out of every town of Galilee, Judea, and Jerusalem.
And the power of the Lord was present to heal them (the multitudes).
Hebrews 10:38
... how God anointed Jesus of Nazareth with the Holy Spirit and with power,
who went about doing good and healing all who were oppressed by the devil,
for God was with Him.
It is also my understanding that Jesus was NOT "fully man"
because since he was "without sin", he did not have man's sin nature.
