18 Aug The Third Person in the Trinity: Scriptural Data 
1 Cor 6.19 – a temple of the Holy Spirit…would this be idolatry of the Holy Spirit if he were not God. In other words, Paul would be encouraging us to be temples to an idol!
Heb 3.7 – The Holy Spirit says, “Today if you hear his voice…” This is citing the Old Testament reference to Psa 95.9-11. In these verses YHWH makes it explicit that they sinned against him. This is YHWH speaking and the preacher of Hebrews says it is the Holy Spirit. (see also Heb 4.6-7)
Heb 10.15 And the Holy Spirit also bears witness to us; for after saying,
16 “This is the covenant that I will make with them
after those days, declares the Lord:
I will put my laws on their hearts,
and write them on their minds,”
17 then he adds,
“I will remember their sins and their lawless deeds no more.”
Is this a mere slip of words? Doubtful. This is cited from Jer 31. The Lord speaks of a New Covenant that he will ratify and make effective by giving new hearts. This is done by God. The preacher of Hebrews makes it clear that the Holy Spirit is God in v.17 when he attributes remembering their sins and lawless deeds no more to the Holy Spirit’s activity. Additionally, the Holy Spirit is called “he.” I will discuss this aspect of spirit being equivalent to personhood in the next post.
