Among the greatest Godly leaders mentioned in the Bible are also the greatest failures as fathers. That seems like an impossible paradox. How can a man be great in his relationship with God while he is an utter failure in his home? But the mystery of truth is that such paradoxes do happen.
In all relationships, except one, you have to grow in love over the years. When a young man falls in love with a woman, that love is only a small fraction of the bond that he will have for her when she is his wife. In fact, their love for each other doesn't reach full bloom until years after they first met.
