The "God showed up" language makes me nervous. I think He is always "showing up" the bigger problem being that we don't recognize and respond to His presence.

He is constantly initiating worship (John 4 "seeking worshipers" in active tense in Greek), we are not always aware or responding. This changes my perspective as WL from getting God to show up to helping people overcome the obstacles to their awareness of His presence and activity.

He reveals...we respond.
That's prett much what I said. Good post.
