I don't know that one knows if there is spiritual warfare. We pray and it occurs depending on what we're praying about but I don't know that we purposely go into warfare. For example, look at Daniel. He did not know why his prayer was delayed but it was revealed to be because of the warfare in heaven. We know that it goes on and when we're up against adversity, we can assume it is part of warfare. Don't know if this helps or if it adds to the confusion.
