THE SET APART SPIRIT (RUACH HA KODESH- רוח קודש) is the mental power of Elohim projected to accomplish His will. Thus Paul compares it to the “mind of יהוה”.
It is the invisible dynamic force or intellectual pressure of the Father that is shared with the Son (1 Corinthians 2:11, 13, 16; Isaiah 40:13; Luke 24:49 John 3:8; 14:17;15:26; 1 Corinthians 2:10-16)
