^In My Name^?
Jesus is telling His disciples that the name of the HolySpirit is Jesus just as He did in Mat 28:19.
The name of the HolySpiritFather is Jesus because the HolySpirit is the SpiritOfChrist Jesus Mat 1:18,20 Joh 10:30.
Jesus is instructing His disciples about the source of the Word - His HolySpirit. Jesus spoke by inspiration of the HolySpirit. When the HolySpirit is in us, we can speak His Words by His inspiration and authority.
The HolySpirit comforts us and teaches us and reminds us of the specific scriptures to meet the situation at hand.
No self confidence, no education, no intelligence can make up for the lack of the HolySpirit involvement in our lives and work.
