God rituals open up the domain the Gods reside over in front of you. If you are spiritually clean and open, it is possible to use a God's power. This is Theurgy and it was practiced in ancient times. One must however use this power correctly and in accordance to the God's will.
@aestheticsguyy I don't have a picture just a food for thought: why can't chritstians communicate back and forth with God when in ancient times this was common practice?
