How privileged and exalted a thing it is to be a father - it images God himself. If children do not have a good image of their earthly father to start from, it will be much harder for them to come to know God as a loving heavenly Father. Saint Augustine had a very bad relationship with his father, and he could not bring himself to address God as Father for a long time. Every father is a priest, like it or not, a good one or a bad one, mediating an image of God to his children.
Peter Kreeft, Fundamentals of the Faith
It is a great responsibility that God has given each one of us who are fathers. Our kids are first of all His children, for all eternity. The greatest and most important job each one of us has is to raise our kids to love their Heavenly Father. We do this in our actions. Great responsibility.
Saint Joseph Pray for us!
