I also don't know how to put it across with concrete evidence.
However in my opinion -
The service overall from start till end was very 'spirit
led'.
They believe that Holy Spirit doesn't function in a ritual
formula.
Worship service have alot of speaking and singing in tongues.
Prophesy(and Tongues) will be spoken during Worship by worship, and
by Senior pastor/service leader during offering time, closing of
service.
The church focuses on Missions and Prophesy - they endorse on Mary
K Baxter and other prophetic preachers to their church to preach.
(You can read up in their website, schedule/special guest
section)
Yup, that's all from me.
