For this sermon, we are in the Biblical book of Philippians and feel the import of Paul referring to Timothy's work with him being "like a son with his father."
Being a dad is a good and glorious reality, but not because Hallmark says so once a year. The earthly fatherhood that we experience is rooted in a prior and deeper and holier Fatherhood. And the way that God is Father to His sons and daughters needs to shape the way we are to ours.
Philippians 2:19-24
