Place the child in a cage with a cuddly animal for several days. Dark, and all alone except for the animal they will bond with it. Then several days later during a ceremony, they will remove the child and animal from the cage, kill the animal and force the child to eat its heart. That's damage the child will never recover from...
These people doing the bidding of the evil, need to die to save future victims.
It is with great effort, great blessing, and great support that a child can escape from being born into such an evil-saturated environment - that of Satanic ritual / offerings / play / etc. Even with recovery, there may be much remaining that one may never fully heal or recover from - combinations of dreams, phobias, startle responses, trust, body responses, physical injuries, etc.
With God, with loving support, with time - it is amazing how much healing and recovery is possible, and how much good can come out of the resultant life.
On the secondary topic - copulation between man and spirit - the scriptures allude to it two different times. The first, in the time of Noah when "every thought of every person was continually on evil" (Gen 6:5) The second was after the flood in the land of Canaan where there level of evil was an abomination.
Scriptures infer the result of such evil and "inter-species" copulation was the Nephilim, literally the giants (e.g., Goliath). Gen 6:4 says that such giants were on the earth "in those days [of Noah] and afterwards" - after the flood [in Canaan.]
I do not see that we have had evil of such magnitude yet today - but I would not be surprised if we get there. We are definitely headed that way.
We are in need of revival.
Well, buckle up because we're getting one––on a scale like nothing the world has ever seen. It has actually already started, but be aware that there's going to be a bit of house cleaning as it ramps up.
