BOOK: The Person and Ministry of the Holy Spirit
Chapter 1.4: Holy Spirit as a Person

1.5    Holy Spirit as a Person

The Holy Spirit sent Jesus:             
Isaiah    48:16              
Come ye near unto me, hear ye this; I have not spoken in secret from the beginning; from the time that it was, there am I: and now the Lord God, and his Spirit, hath sent me.
The Holy Spirit speaks:
Acts     13:2
As they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work whereunto I have called them.
He has a will:
1 Cor 12:11
But all these worketh that one and the selfsame Spirit, dividing to every man severally as he will.
He has feelings: 
Eph 4:30
And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
