In Gospel-Powered Parenting William Farley writes, "If you ask parents what is the most important thing they can do to raise children who will follow Christ, some will mention adequate discipline, others enrollment in a Christian school, still others the importance of home-schooling or Bible reading. They rarely mention example. Yet example is the first principle of parenting. This should not surprise us. Parenting is about leadership, and example is the first principle of biblical leadership. When parents practice what they teach, God gives them moral authority in their childrens' eyes. All the teaching in the Bible starts with example."
Farley goes on to show that our marriages are the primary realm where our kids need to see the gospel modeled. He writes, "The message that our marriage preaches either repels or attracts our children. God wants your child to watch your marriage and think, 'I want a marriage like that, and I want the God that produced it.' Or, 'When I think of the beauty of the gospel, I think of my parents' marriage. I want to be a part of a church that is loved by God the way my dad loves my mother. I want to be part of a church that finds its joy in submitting to Christ as my mother joyfully submits to my father.'" (pp. 107 & 111)
