I was personally involved in the threat against black magic and its practitioners. They are much more dangerous than people admit or even imagine. There are persons in positions of power who use it. We found that most people who die from black magic attacks die from heart attacks or suicide. We saw it numerous times. Does that sound familiar?
I agree with much that you say, having been a target of it most of my life.
I’ve found a solution that works very well. I pray for them and send them love. They hate it. I imagine a bubble of loving light around them.. They hate it even more.
I’ve noticed that by doing this the more they try to cause harm to others the more they self destruct.
Technically, if you follow J.C. you dont have to worry about black magic.
Sadly, Good allows Satan to have a lot of power on this earth.
