The Holy Spirit is part of the triune nature of God, but the Holy Spirit also has an individual personality. The Bible reveals that the Holy Spirit…
HAS A MIND:
And He that searcheth the hearts knoweth what is the mind of the Spirit… (Romans 8:27)
SEARCHES OUT THE HUMAN MIND:
But God hath revealed them unto us by His Spirit; for the Spirit searcheth all things, yea, the deep things of God. (I Corinthians 2:10)
HAS A WILL:
But all these worketh that one and the selfsame Spirit, dividing to every man severally as He will. (I Corinthians 12:11)
The will of the Holy Spirit guides believers by denying permission for certain actions:
Now when they had gone throughout Phrygia and the region of Galatia, and were forbidden of the Holy Ghost to preach the word in Asia,
After they were come to Mysia, they assayed to go into Bithynia; but the Spirit suffered them not. (Acts 16:6-7)
The will of the Holy Spirit also guides believers by granting permission:
SPEAKS:
He spoke to Philip:
Then the Spirit said unto Philip, Go near, and join thyself to this chariot. (Acts 8:29)
He spoke to Peter:
While Peter thought on the vision, the Spirit said unto him, Behold, three men seek thee. (Acts 10:19)
LOVES:
Now I beseech you, brethren, for the Lord Jesus Christ’s sake, and for the love of the Spirit, that ye strive together with me in your prayers to God for me. (Romans 15:30)
INTERCEDES:
One of the personality traits of the Holy Spirit is that He is an intercessor. This means He prays to God on behalf of others:
Likewise the Spirit also helpeth our infirmities; for we know not what we should pray for as we ought; but the Spirit itself maketh intercession for us with groanings which cannot be uttered [spoken]. (Romans 8:26)
