I believe that the Spirit of Truth of which Jesus speaks regarding in John 14-16 is the one way which God still speaks to us. How is this Spirit manifested? Various ways.
For starters, I believe that God pushes us (and yes, that is a way of speaking) through Science and Scholarship. Science pushes us to examine our world (and for us panentheists, you know what that means), our universe, and into a deeper philosophical discussion about the nature of reality. I tend to follow the laws of thermodynamics a bit and believe that for now, they define the physical universe. So, sometimes, I sit and mediate upon them and how they tell us about God. Science has pushed us into looking at medicine, miracles, and a host of other issues, which, if we listen, we will see that God is speaking us forward.
Scholarship does much the same thing with Scripture. We struggle with it. Exodus has nearly none to none evidence to support it as the biblical account states it. Genesis has been shown not to be about Creation. Paul didn’t write all the Pauline books. This has propelled our faith forward, and in some ways, backwards (which is sometimes a good thing when you need an anchor). Many of us are moving to a more holistic faith, focusing on Church Tradition while still holding to Scripture. The Spirit dwells in the Church, but only speaks through the Scripture. We are moving to regain a hold in Tradition, some of us, whether it is the Tradition of the Patriarchs or the Reformation. We realize that we have gone far off base with literalism and fundamentalism.
Does God still speak in visions and dreams? Of course. I mean, how else does the Divine inspire us to pursue change, justice, science and scholarship? Further, when we get beyond the patina of our ill-formed traditions, the Spirit can once again speak through the Scripture.
