... I am predestined to walk down the street and not trip on the pebble ...
Hmmm ... I've applied my flea brain to this one and come to the conclusion that the difference between FATE and DESTINY is more than just semantic.
Free will allows us to control our own fate. You can decide which side of the street you walk on.
But not the day of your birth or, I believe of your death, or the children you will have, etc. Those things are destiny.
You know, like Christopher Reeve was paralysed in a riding accident. He might think: Oh, if I hadn't done that ...
But if he hadn't been on that horse, perhaps he would have been hit by a car or something, that day. Somehow God needed that to happen to him, for his soul's development, which is what we're really here for?
The common theme of all religions is that we're not in this world for fun.
There was a time in John Lennon's life apparently, when he'd just walk across the road through New York traffic without looking, to the screeching of tyres and blasting of horns, testing the belief that he wouldn't die that day unless he was meant to.
And when he did die, he was shot in the back on his way to the corner shop for milk. Nothing he could have done about it.
Perhaps by exercising our free will wisely, in the direction of inner not outer things -- being 'in but not of the world' -- we may be able to soften certain hard strokes of destiny.
Something like that?
EDIT: Huttman, sorry I didn't ignore your post but found nothing to add to it. Agree fully ...
