Some things HS does (in man):
- HS reveals the things to come
And there was a man in Jerusalem whose name was Simeon; and this man was righteous and devout, looking forward to the consolation of Israel; and the Holy Spirit was upon him. And it had been revealed to him by the Holy Spirit that he would not see death before he had seen the Lord’s Christ. (Luke 2:25-26)
And his father Zechariah was filled with the Holy Spirit and prophesied... (Luke 1:67)
No prophecy was ever made by an act of human will, but men moved by the Holy Spirit spoke from God. (2 Peter 1:21)
- HS teaches people
For the Holy Spirit will teach you in that very hour what you ought to say. (Lk 12:12)
- HS testifies of Jesus
But you will receive power when the Holy Spirit has come upon you; and you shall be My witnesses both in Jerusalem and in all Judea, and Samaria, and as far as the remotest part of the earth. (Acts 1:8)
And we are witnesses to these things, and so is the Holy Spirit, whom God has given to those who obey him. (Acts 5:32)
- HS guides into all truth
By referring to this, when you read you can understand my insight into the mystery of Christ, which in other generations was not made known to mankind, as it has now been revealed to His holy apostles and prophets in the Spirit. (Ephesians 3:4-5)
But, as it is written, “What no eye has seen, nor ear heard, nor the heart of man imagined, what God has prepared for those who love him” — these things God has revealed to us through the Spirit. For the Spirit searches everything, even the depths of God. (1 Corinthians 2:9-10)
