What testimonies? The Gods are too powerful to possess someone. If they did, the human's nervous system would be fried, and they would remain a vegetable after the God leaves. Even the least powerful God is too much for a human body to handle.
That proves that possession is done by the enemy, not by our beloved Gods.
And who cares about uneducated depictions from ignorant people and shills? Those hold zero factual value. They're just abstractions, perversions of their minds.
