Was Jesus still God while He walked the earth, the answer must be yes or no.
Of course He was. Not only that, He was
fully empowered IN HIMSELF to do whatever the Triune God desires and designed to do.
Jesus did not need to tap into or borrow or be gifted power from the other members of the Trinity to do anything. Ever.
Luk 5:20
And when he saw their faith, he said unto him, Man, thy sins are forgiven thee.
Luk 5:21
And the scribes and the Pharisees began to reason, saying, Who is this which speaketh blasphemies? Who can forgive sins, but God alone?
Luk 5:22
But when Jesus perceived their thoughts, he answering said unto them, What reason ye in your hearts?
Luk 5:23
Whether is easier, to say, Thy sins be forgiven thee; or to say, Rise up and walk?
Luk 5:24
But that ye may know that the Son of man hath power upon earth to forgive sins, (he said unto the sick of the palsy,) I say unto thee, Arise, and take up thy couch, and go into thine house.
Jeus is fully in control of the situation. As He always is.
Jhn 18:6
As soon then as he had said unto them,
I AM ("
he" is not in the text), they went backward, and fell to the ground.
