In conversations I've had with relatives I have been very surprised to hear ideas that are or stink of predestination.
I am talking about such things as, "What will happen, will happen" or "[If] it is meant to be" or if you are Greek, more often than not, "Its my destiny".
This leads then to people thinking that they are powerless to fight it and they take risks. Like my brother, who after having just lost a niece, is driving around with no sleep! I think, his thinking is that he is not destined to go just yet!!
Admittedly it is due to ignorance but how to make these people stop seeing it in that light? Talking theology with them is not helpful.
