"But I tell you the truth: It is for your good that I am going away. Unless I go away, the Counselor will not come to you; but if I go, I will send him to you." -John 16:7Jesus refers to the Spirit as "him".. because He is a person who can comfort and counsel us in a intimately personal way.
In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us with groans that words cannot express. And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for the saints in accordance with God's will. -Romans 8:26-27This passage tells us that the Spirit has a mind, He knows God's will and intercedes for us to that end. He is capable of thought and intercession.
All these are the work of one and the same Spirit, and he gives them to each one, just as he determines. -1Corinthians 12:11This verse shows us that the Spirit has a will.. He gives gifts as He wills.
Well, I told you that this would not be exhasutive. Let me know if you agree or not.. and feel free to add scriptures to mine or pose alternate views.
