As fathers, we have a responsibility to teach our children correct principles. If we do, we will equip them for the time when they have children of their own.
Some have asked, why does this passage say our children "will not depart from" the things we teach them? Are we depriving them of their agency by teaching them the Gospel or other things we believe to be true? I don't think so. However, I do believe that it means when we teach our children the Gospel, it will stay with them, even if they wander away from it. The choice will need to be their own, but the opportunity to return will always be open to them if we do our duty as parents and teach them by word and by example.
Happy Father's Day!
