POSITIVE & NEGATIVE

When I was growing up,I remember Daddy telling me to make sure I put the negative cable to the positive side, and the positive cable to the negative pole, if I were going to recharge them! Otherwise, it just wouldn't get "jumped".....
Made sense to me, but even more so, did it make sense, when I thought about how Christ could also be "THE" cable of influence over a husband and wife, when one is more negative, and the other is more positive.....
He IS the balance between the two, and also for each one,individually!
