Oh?
And just HOW do you make THIS judgment call?
What is your STANDARD you base their messages upon?
You should have kept reading before clicking on "Post Reply". It was the next sentence. Please allow me to repeat myself:
"I figure that anyone or anything that puts a few cracks in the walls we build around our hearts is of value."
I'm a rather simple fellow in this regard and there's really no need to make it complicated, imho.
We humans are like self-tuning receivers. We have freewill and can tune in to any "channel" we find interesting by using our thoughts, interests, focused attention through music, reading, philosophy, other people, etc.
The name of the game is to choose the best channel and, to me, the best channel is the God Channel and, as near as I can tell, our heart is the signal strength meter.
As such, anyone who can help you tune your inner receiver this way can be of value if you have the right focus and attitude (the right sort of spirit). If so, the God channel is easy to find and tune in.
It's all up to you, the receiver, to choose what to receive. You alone have this power over your freewill and what you tune in.
Seek and ye shall find, so choose wisely.
