The trust I experience in my life does not come from the world or other people, be they loved ones or authorities, but from within myself. There is a truth in me that allows me to trust in others which most of us know as God or Christ.
I cannot get inside your skin or you in mine, but the creator/animator of the universe lives within me and I can know “It”, (God) well if I’m quiet and try. So, oddly enough, I have the whole of the universe in me, (God, one indivisible truth or spirit) but I can’t really trust you without Its help? I would guess this is the price I pay for the illusion of complete freedom, space and time; it’s an interesting bargain and an amazing teaching tool.
