if you tried to tell people 500 years ago that there are these tiny things called germs and viruses that are tiny living things that can kill you, they would have thought you are crazy; yet it is true. Same thing is with regards to the spirit realm.
You believe the invisible?
You believe in gravity?
It is invisible. And what precisely is it?
“I don’t know.”
So you believe in an invisible force that you don’t even know what it is. I believe in one that I do know what it is.
