Taken from a book (which can be read online here) from Mark Driscoll:
"Your children and your wife are your first ministry. You must begin at home. Then you can work out from your home to invite strangers in to see the difference Jesus makes in the life of a man, his wife, and their children. Isaiah 8:18 says, "Behold, I and the children whom the Lord has given me are signs and portents in Israel from the Lord of hosts, who dwells on Mount Zion." Isaiah rightly understood that in dark days, it is men who love God, love their wives, and raise their children with wisdom, grace, and joy who shine forth like the first rays of dawn.
More than bigger governments, bigger schools, more free school lunches, more child therapists, more child medications, more daycares, more prisons, and more birth control, we need more godly men who raise their sons to be godly men who raise their sons to be godly men who raise their sons to be godly men (Ps. 78:5-8)."
