"But when the Comforter is come, whom I will send ... even the Spirit of truth ... he shall testify of me" (John 15:26)
Who is the Holy Spirit? The Spirit of God, existing in another mode of being than ourselves. He exists as a spirit and not as matter, for He is not matter, but He is God.
He is a Person. It was so believed by the whole Church of Christ down through the years. It was so sung by the hymnists back in the days of the first hymn writers. It is so taught in the Book, all through the Old Testament and the New.
Now what follows from all this? Ah, there is an unseen Deity present, a knowing, feeling Personality, and He is indivisible from the Father and the Son, so that if you were to be suddenly transferred to heaven itself you wouldn't be any closer to God than you are now, for God is already here.
Changing your geographical location would not bring you any nearer to God nor God any nearer to you, because the indivisible Trinity is present.
People grow on us, and the Holy Spirit, being a Person, can grow on us.
It is certainly not speculative that God is able to manifest Himself most in the lives of those who passionately love Him.
