God is that reality that occurs time and time again when I pray because I want to---not having to ask for anything or repent for anything always...but just to cheerfully and willingly open myself up to a trusted friend. The confirmation is not always a felt emotion--yet I acknowledge the presence.
More often, it happens with other believers...where one ordinary guy will say something profound that you know he did not think of!
The confirmation, if it can be observed at all, comes through the actions of others---many of whom don't even go to church!
