I've known people who, to the outward appearance, looked to be the most upstanding, finest pillars of the community imaginable yet I felt an icy chill of dread run down my spine when meeting them.
Occasionally, years later, what I 'felt' was borne out when they were arrested for some crime or other.
[usually involving children]
I can't really recall getting that 'feeling' off anyone obviously or socially considered "bad", such as street beggars or the like.
It's mostly from the "good" people.
Odd, isn't it?
[then again, it makes more sense to hide in plain sight, I reckon]
I say the witness of the Holy Spirit was strong in you at those moments!
Some of us who were born before 1970 have the privillage to read old wise tales etc and ledengs from others countries than a period came it was so poopooed.
but I got a feeling much is still with us and our ignorants won't make it go away, but leave us vulnerable or subjected too!
That is why praying and reading the scriptures daily is vital in evenyone life to fortify and to put on the armor of God and exercise discernment!
