Although you can fool the people at church part of the time, and you can fool yourself all of the time, you can't fool members of the family any time.  The base unit of society is the home.  It is logical, then, that living the Christian life must first and foremost be done at the level of the family.  It is in our home that we put Christian living into practice.  Our home is the laboratory for practical godliness.  At times it may be difficult to live our faith there, but we mustn't give up.
