Of course Jesus and his God are one .... EXACTLY like ALL believers are one with God, and God's anointed:Oh oh oh! And also, "I and My Father are One." John 10:30
John 17:20-21 Neither pray I for these alone, but for them also which shall believe on me through their word; 21 That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
