If the Holy Spirit is a Thing, How Does "It" Intercede for Believers?

"The Scriptures give clear evidence that the Holy Spirit is a person, not an impersonal force. The Holy Spirit has intellect (He knows the deep things of God-1 Cor. 2:10), sensibility or emotions (He can be grieved-Eph. 4:30), and will (He gives gifts as He wills-1 Cor. 12:11). No impersonal force has intellect, emotions and will. He also does things no impersonal force can do-He teaches (John 14:26), intercedes (Rom 8:26), calls (Acts 13:2), directs (16:6,7), and empowers (Rom. 15:19). The deity of Christ is also clearly established in the Scriptures. He is the Creator of all things (John 1:3; Col. 1:16), which reveals His omnipotent power as the eternal Son of God. However, He voluntarily gave up the manifestation of His attributes in order to take on Himself the form of man and to die on the cross for the sin of the world (Phil 2:5-8)."

When I read this I thought this has to be one of the most elegant rebuttals against Herbert Armstrong's anti-Trinitarianism I have ever read.
