We do not have proofs, they are not proofs.
What we have in life is a plug, a plug that can come from previous lives or it can come from short circuits that we have created in this life.
What does it mean "stopper", in reality they are spirits that adhere to us, usually they are spirits of pride, of jealousy, of excessive ambition, those adhere like tar to the skin.
The Creator wants to take away these spirits that do not let the blessing go down, then he makes us go through situations that take off those spirits, so, a situation of humiliation takes off a spirit of ego, it is not a test, it is a spiritual surgery to remove it the plug and the blessing can enter.
Every time we pass a test it is not that God punishes us, it is that it is helping us to take off a spirit that has adhered to us and it usually hurts us a lot because it does not let in the blessing.
