Not everyone has a good dad, but I do. The “how much more” argument for God’s love strikes me in a deep way: If my dad loves me this much, then how much more does God love me? For those of you who had a bad dad, the argument can work the other way: Because God loves you, your dad ought to have loved you.
Jesus assumes that even the best of dads are evil, and even bad dads have a modicum of love for their children. This is how he argues:
“What father among you, if his son asks for a fish, will instead of a fish give him a serpent; or if he asks for an egg, will give him a scorpion? If you then, who are evil, know how to give good gifts to your children, how much more will the heavenly Father give the Holy Spirit to those who ask him!'” (Luke 11:11-13)
It is an awesome thing to be a child of God:
“See what kind of love the Father has given to us, that we should be called children of God; and so we are.” (1 John 3:1)
But this is not by natural birthright. It is by grace and adoption and rebirth:
“But to all who did receive him, who believed in his name, he gave the right to become children of God, who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.” (John 1:12-13)
