So the father knew that it was at that hour in which Jesus said to him, "Your son lives." He believed, as did his whole house.
And his whole house ...  What a weight of responsibility rests upon every father.  From the time of Adam who, as the federal head of the whole human race, plunged mankind into ruin, it has been a solemn and undeniable fact that whole families, cities, and even nations, partake of the consequences of a single decision for right or wrong by a single individual.  The decision of this father brought redemption to an entire household.
