From Luke 11:11-13, It is clear that God the Father is the ideal father, unparalleled by our earthly fathers. It is important to note that all human fathers originate from God, Ephesians 3:14-15 “For this reason, I bow my knees before the Father, 15 from whom every family in heaven and on earth derives its name.”
Every child has an expectation to receive from their fathers and in most circumstances, we come short and that's why we should ultimately look up to our heavenly Father. By this, our expectations are met and we can be able to forgive every shortcoming of our earthly fathers.
We can forgive because God the Father gave us the best gift of all when He gave us His only begotten Son. Romans 5:8 says, “But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us.”
Francis concludes by saying that We could/might have been disappointed by a [earthly] father, but God is our Heavenly Father who does not fail. It is therefore imperative that we receive His gift to us
