Your family life needs to fit into a larger purpose, a purpose that is comprehensive, constructive, and cohesive. That purpose can't leave out the family nor destroy it. But your family should never be confused about who is most important in your life. And that is neither yourself nor them.
Unless the LORD builds a house, the work of the builders is wasted. Unless the LORD protects a city, guarding it with sentries will do no good. - The Bible (Psalm 127:1)
