Friends, today’s Gospel tells us to love our enemies so that we may be like the Father. What is the Father of Jesus Christ like? Well, listen: “He makes his sun rise on the bad and the good, and causes rain to fall on the just and the unjust.” The Father of Jesus Christ is love, right through. That’s all God is; that’s all he knows how to do. He is not like us: unstable, changing, moving from one attitude to another. No, God simply is love.
In every case, his grace comes first, and grace is all that he has to give. This is why the comparison to the sun and the rain is so apt. The sun doesn’t ask who deserves its warmth or its light before it shines. It just shines, and both good and bad people receive it. Neither does the rain inquire as to the moral rectitude of those upon whom it showers its life-giving goodness. It just pours—and both just and unjust people receive it.
