Your thread opened up the issue brought up since the discussion is specifically about the Holy Spirit. You would be amazed how many Creeds exist and they're based off of the Nicene Creed as a guideline.
But just like the example I gave about hearing what person to give to and tell them God loves them came From God but it was delivered to me through the Holy Spirit living within me. The men who wrote the Bible experienced similar process. God told Moses in the mountain, the other Prophets would do as instructed or said and then we read the story about how it happened and the results. God is the same then as now.
In my opinion it's Ok to have specific Conversations and topics in Our Life With God. One topic, for example is How Can we keep from sin in a sinful world?" . Another could be, "How can we find God's will for Our Lives"? I'm not changing this post to those topics but am expressing I believe it's totally fine to focus on a subject totally on One part of God, such as the Holy Spirit and have a discussion to get closer in that area. I am not leaving out God the Father, Or Jesus Christ out of the Conversation. But focusing On Our relationship with The Holy Spirit in which, The Bible clearly states speaks to us and The Topic is, " How do you hear From The Holy Spirit in your walk with Jesus" . Their seems to be some conflict with you that I sense that you seem to believe the Holy Spirit does not speak to the believer in which is false. The Holy Spirit does speak to us.
