It has been suggested that a person becomes "elect" by God when his genome (chromosomes, DNA, et al) line up a certain way. This makes election to be less "capricious" - God just saying, "you, you and you I love; the rest go to hell". It also would tie in to families - chances of the "right" factors in children of children of children of the elect, etc. Odd thinking today. When I take a break from mowing the lawn, the brain keeps a chuggin' along!
