John 3:8 (HCSB)
8  The wind blows where it pleases, and you hear its sound, but you don’t know where it comes from or where it is going. So it is with everyone born of the Spirit.”

Bernard Ramm commented, “To profess to know a great deal about the Spirit of God is contrary to the nature of the Spirit of God. There is a hiddenness to the Spirit that cannot be uncovered. There is an immediacy of the Spirit that cannot be shoved into vision. There is an invisibility of the Spirit that cannot be forced into visibility. There is a reticence of the Spirit that cannot be converted into openness.”

How do we know when the Holy Spirit is speaking to us?  What does it mean when people say that “he spoke to my heart?”  The Spirit guides us in ways that are mysterious and varied.

If we fail to acknowledge this mystery, we either reduce God’s working to a formula that will cause us to miss the Spirit’s movement in our lives, or we become over confident in what we think He is saying to us.  The danger here is that we are giving our subjective feelings the same authority as that of Scripture.
