1) The Holy spirit is not a blob of spirit that attaches itself to you when you become saved.The Holy spirit is like "the wind" (John 3:8). He is everywhere in the spacio/temporal realm(s). When a believer is saved [receives Christ], their heart is opened up to the truth [beauty] of the Gospel. The Holy spirit convicts believers, brings them truth, motivates them, refreshes them, comforts them, and teaches them based on the riches of God's glory. Check these verses out.
We do, however, speak a message of wisdom among the mature, but not the wisdom of this age or of the rulers of this age, who are coming to nothing. 7 No, we declare God’s wisdom, a mystery that has been hidden and that God destined for our glory before time began. 8 None of the rulers of this age understood it, for if they had, they would not have crucified the Lord of glory.However, as it is written:
“What no eye has seen,
what no ear has heard,
and what no human mind has conceived” —
the things God has prepared for those who love him—
these are the things God has revealed to us by his Spirit.
The Spirit searches all things, even the deep things of God. For who knows a person’s thoughts except their own spirit within them? In the same way no one knows the thoughts of God except the Spirit of God. What we have received is not the spirit of the world, but the Spirit who is from God, so that we may understand what God has freely given us."
So, the realization for me here is that the Holy spirit isn't something which comes and attaches itself to me as soon as I receive Christ, but rather the Holy spirit is everywhere, He is God Himself (the third member of the Trinity), and he glorifies himself in my heart. The Holy spirit teaches believers when they read the Bible (and think about life), and that is how God's teachings are "written on their hearts", rather than on paper.
The reason I emphasize the Holy Spirit so much in my writings is because I've realized how dead we are without Him. The Holy spirit is the only thing that can open our hearts to the real truth of something. Without the Holy Spirit, all Jesus is to us is an old, boring church story, the Christian Faith is dead to us, and we can't grow.
