“God the Father makes perfectly good sense to me, and God the Son I can quite understand, but the Holy Spirit is a grey, oblong blur!” (Quote, source unknown.)
The Holy Spirit bears at least three characteristics of what makes a person a person: Intellect, Feeling, and Will.
Firstly, what does the Bible say about His intellect: For who knows a person’s thoughts except for their own spirit within them? In the same way, no one knows the thoughts of God except the Spirit of God. (1 Corinthians 2:11)
A ‘grey, oblong blur’ does not know the thoughts of God!
The Holy Spirit has access to the deep things of God that no human or entity has. Furthermore, He knows what’s in our thoughts: And He who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for God’s people in accordance with the will of God. (Romans 8:27) The Holy Spirit has full access to God and full access to me and you, there is nothing in our lives that he does not know. Nothing.
Secondly, what about His feelings: And do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption. (Ephesians 4:30) The context of this verse is immorality and wrong language. When we are tempted to act and talk like the world that is outside of His Church, it grieves the Holy Spirit. For example, when we are tempted to Gossip, lie, and slander. Those of us that have this intimate relationship with the Holy Spirit immediately sense the presence of someone who is not pleased with what’s happening. It grieves Him. A ‘grey, oblong blur’ or a ‘symbol’ does not grieve.
Finally, the Holy Spirit also has a will: All these are the work of one and the same Spirit, and He gives them to each one, just as He determines. (1 Corinthians 12:11) Out of His will, He does many personal acts:
- He speaks – Acts 13:2 initiates ministry of Paul and Barnabas: While they were worshipping the Lord and fasting, the Holy Spirit said, “Set apart for me Barnabas and Saul for the work to which I have called them.” (Acts 13:2)
- He testifies – John 15:26 bears witness to Jesus. He gives testimony about Jesus: “When the Advocate comes, whom I will send to you from the Father, the Spirit of truth who goes out from the Father, He will testify about me. (John 15:26)
- He teaches – But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you. (John 14:26)
- He convicts – When He comes, He will prove the world to be in the wrong about sin and righteousness and judgment. (John 16:8-11)
- He intercedes for us – 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 through wordless groans. (Romans 8:26)
- He Guides and directs us – But when He, the Spirit of truth, comes, He will guide you into all the truth. He will not speak on his own; He will speak only what He hears, and He will tell you what is yet to come. (John 16:13)
So we know and have read in Scripture, that He is a person with intellect, feeling, and will. These all give rise to the attributes of God, and because the Holy Spirit dwells within us, we cannot help but develop these same attributes which are the Fruit of the Spirit: But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control. (Galatians 5:22-23)
