Even though the influence of dads on their children's lives is not a superpower (something unusual), it is one of the most powerful forces in a child's life. Would this daughter have been moved so deeply by any other member of the military?
God connects dads to kids and kids to their dad at a very deep level.
Why does God give that power to dads?
Because God loves children and He wants you to experience some of His love through me, your dad.
God made us dads to be the head of the family, and He gives me the authority and power to love and bless you in a special way.
