We had an interesting sermon yesterday on hearing from God that was almost Pentecostal; however, it was seated in a more grounded framework of an unchanging God not shutting His trap two millennia ago.
Before you get all worried about Scripture getting trumped, an unchanging God won't be changing the truth, either. If what you hear from the Holy Spirit is something that goes counter to scripture, then it might be last night's burrito platter rather than the Spirit.
If God is speaking to our spirit, are we listening? Better yet, do we want to listen? If He is saying things that are uncomfortable, we might opt to become a cessationist-by-convience and discount the idea of God talking to folks in the present age.
