Arm, finger etc are in reference to the Holy SpiritIsaiah says Jesus, not the Holy Spirit is the arm of the Lord, wotsup.
Belief and Unbelief Among the Jews and wotsup
37Even afterJesushad performed so many signsin their presence,wotsupstill would not believe in him.38This was to fulfill the word of Isaiah the prophet:
“Lord, who has believed our message
and to whom hasthe arm of the Lordbeen revealed?”
39For this reasonwotsupcould not believe, because, as Isaiah says elsewhere:
40“He has blindedwotsup'seyes
and hardenedwotsup'sheart,
sowotsupcan neither see with his eyes,
nor understand with his heart,
nor turn—and I would heal him”
Jesus says I, not the Holy Spirit, do the things as the finger of God, wotsup.
14Jesuswas driving out a demon that was mute.18If Satanis divided against himself, how can his kingdom stand?Isay this because you claim thatIdrive out demons by Beelzebul.19Now ifIdrive out demons by Beelzebul, by whom do your followers drive them out? So then, they will be your judges.20But ifIdrive out demons bythe finger of God,then the kingdom of Godhas come upon you.And you still don't understand that a Son of God is God.
Like the son of a human being is a human being.
