Christine is on a roll; her third installment in the series on understanding the heart-led way discusses gates and filters in our human perception. I would reinforce her statement that such things are simply a part of us, but that we are far better off being more aware of them.
On a related note, I can testify that one of the nastiest problems I carried around for years was a huge load of emotional wounds. I was born highly sensitive to human vibes of that sort and easily hurt. Unfortunately, I grew up in a family and subculture that made it a sin to be sensitive like that, so I got no good training on how to turn it into a talent.
It was part of what pushed me near suicide repeatedly until I was near forty years old. There were a lot of things that worked toward my healing, but I assure you that discovering the heart-led way was rather like the crescendo of the symphony that made life worth living, even while I’m quite eager to go be with my Savior. I knew Him as my Savior long before that (age 9) but I could never hear His voice until I knew to listen with my heart.
