God is source:

The source of the Holy Spirit is out of the triune, the trinity of God. Systematic Theology, The study of the this Triune: God the Father, Jesus the Son, and The Holy Spirit is deep waters.   John Wesley states, ”There are three that bear record in heaven, the Father, the Word, and the Holy Ghost: And these three are one.” Referring to 1John 5:7

 John Calvin Stated, “"Herein he shows, that all who endeavored to explain it at all, (The Trinity) have utterly lost their way; have, above all other persons hurt the cause which they intended to promote; having only, as Job speaks, "darkened counsel by words without knowledge… Dare not insist upon any one's using the word Trinity, or Person…Though I believe the Father is God, the Son is God, and the Holy Ghost is God; yet I scruple using the words Trinity and Persons, because I do not find those terms in the Bible. I would insist only on the direct words, unexplained, just as they lie in the text: "There are three that bear record in heaven, the Father, the Word, and the Holy Ghost: And these three are one."

I believe this fact also, (if I may use the expression,) that God is Three and One. But the exact manner of how I do not claim to completely comprehend. But I do know no how anyone can be a Christian believer till they have as St. John speaks, "the witness in himself;" till "the Spirit of God witnesses with his spirit, that the are a child of God;" that is, in effect, till God through the holy Ghost witnesses that God the Father has accepted them through the merits of God the Son: And, having this witness, they honor the Son, and the blessed Spirit.

It is through God’s giving of his Holy Spirit and revelation in the Son that we know anything about God.  We hear a child say, “Jesus is in my heart.”  Technically and theologically that is incorrect.  Jesus after his death. Resurrection, and ascension now sits in the throne room of God at his right hand.  It is the Holy Spirit that is in the child’s heart.  But since the Holy Spirit is an exact representation of Jesus, in an effect, Jesus is in their heart.  But even greater, in that when we pray and find ourselves in the Holy Spirit, the Holy Spirit leads us into Christ, and so we find ourselves then praying in the thrown room of God and all the power and all the Glory of Gad falls over us and is available to us!!

Read today Acts 5:29-32; Rom. 8:26-27; 1 John 4:13; Exodus 24:16; Ezekiel 11:17-20 and reflect on the “God” aspect of the Holy Spirit.  Who’s source and presence is found and flows out of the triune of God.

Also, Yesterday I included in my message a “check list” to notice how various aspects of the Holy Spirit is present in your churches Sunday service.  I hope you read it.  If not please go back now and read it.  Then post below as a comment what you discovered about the way the Holy Spirit is presented in your church service.
