I believe God has done that many times, you just don't know it.
"I don't believe God has ever done it, you've just imagined it." See, my statement can be just as assertive and presumptious.
N.Drew, we keep drifting away from the main topic. I don't know what Jesus meant by his "no part of the world" words, I don't know if he ever uttered them, I don't know if he ever existed.
There is an easy, instant way for me to learn and believe. But my parent would rather let me fall of the cliff (in my hardheadidness) than simply use his powers (all of his powers, whatever powers necessary) to reach me.
You must have been a better child, more attentive, more obedient, more attuned. I must have been different, perhaps more rebelious or maybe thick in the head and didn't hear his voice. If my purpose in life is to serve him, why not use a fraction of his great powers and tell me in a way I can hear and believe. He knows what that way is.
And I am not alone. More than 70% of his children are lost, running towards a cliff...
I am only human, but believe me, my parenting is equally devoted to and divided between my children.
