Collin Hansen delivers a message at TGC21 titled “The Duty and Delight of Catechizing Your Children.” He begins with the thesis that someone will catechize your children and follows with the pivotal question, “Will it be you or someone else?”From Deuteronomy 6:4-9, Hansen addresses the nuts and bolts of catechesis, beginning with its theological foundation and detailing how parents might engage in both formal and informal catechesis, as the Scriptures command.As parents lay the foundation of catechesis for their children, duty gives way to delight, while Biblical truth begins to shape their families for the glory of God.
