Lust does not mysteriously appear in the heart of a teenager as though it came from nowhere. Teens are like the rest of us. Lust is part of their Adamic wiring, a sobering call for every parent to cooperate with God in shaping a child’s heart and life to a purer desire that is in Christ alone. This call is more than academic; the parent must model their message, giving their child a living illustration of God’s love to another person. Let me illustrate this point by sharing the fictional account of Biffina that shines a light on a real-world problem that is not fictional in too many of our young people’s lives.
