There are four separate and distinct lines of proof of the Personality of the Holy Spirit.
1. The first line of proof of the Personality of the Holy Spirit is that all the distinctive marks or characteristics of personality are ascribed to the Holy Spirit in the Bible. What are the distinctive characteristics of personality? Knowledge, feeling and will. Any being who knows and feels and wills is a person. Oftentimes when you say that the Holy Spirit is a person, people understand you to mean that the Holy Spirit has hands and feet and fingers and toes and eyes and ears and nose and mouth, and so on. But these are not the marks of personality, these are the marks of corporeity. Any being who knows, thinks and wills is a person whether he have a body or not. Now all these characteristics of personality are ascribed to the Holy Spirit in the Bible.
(1) Turn in your Bibles to 1 Cor. 2:11. +"For what man knoweth the things of a man, save the spirit of man which is in him? Even so the things of God knoweth no man, but the Spirit of God."+ _Here knowledge is ascribed to the Holy Spirit._ The Holy Spirit in other words, is not a mere illumination that comes to your mind and mine whereby our minds are cleared and strengthened to see truth that they would not otherwise discover. The Holy Spirit is a Person who Himself knows the things of God and reveals to us what He Himself knows.
(2) Now turn to 1 Cor. 12:11: +"But all these worketh that one and the selfsame Spirit, dividing to every man severally as He will."+ Here _will_ is ascribed to the Holy Spirit. The thought clearly is that the Holy Spirit is not a divine power that we get hold of and use according to our will, but that the Holy Spirit is a person who gets hold of us and uses us according to His will. This is one of the most fundamental facts in regard to the Holy Spirit that we must bear in mind if we are to get into right relations to Him. More people are going astray at this point than almost any other. They are trying to get hold of some divine power which they can use according to their will. I do thank God that there is no divine power that I can get hold of and use according to my will. What could I, in my foolishness and ignorance, do with a divine power, what evil I might work! But on the other hand, I am still more glad that while there is no divine power that I can get hold of and use according to my foolish will, there is a Divine Person who can get hold of me and use me according to His infinitely wise and loving will.
(3) Turn now to Rom. 8:27. +"And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God."+ What I wish you to notice here is expression, "_the mind_ of the Spirit." The Greek word here translated "mind" is a comprehensive word that has in it the ideas of both thought and purpose. It is the same word which is used in the 7th verse of the chapter where we read, +"The mind of the flesh is enmity against God,"+ where the thought is that not merely the thought of the flesh is against God, but the whole moral and intellectual life of the flesh is enmity against God.
