Here are two verses that come to mind for Fathers' Day.
See the kind of love the Father has given us that we should be called children of God, and that is what we are! (1 John 3:1, Evangelical Heritage Version)
I have no greater joy than when I hear that my children are walking in the truth. (3 John 4, Evangelical Heritage Version)
A blessed Fathers' Day to all our fathers out there.
